- A.Microwave–10⁻² m; infrared–10⁻⁴ m; ultraviolet–10⁻⁸ m; gamma–10⁻¹² m
- B.Microwave–10⁻⁸ m; infrared–10⁻¹² m; ultraviolet–10⁻² m; gamma–10⁻⁴ m
- C.Microwave–10⁻¹² m; infrared–10⁻⁸ m; ultraviolet–10⁻⁴ m; gamma–10⁻² m
- D.The matching shown in choice 4 of the Q1 paper
Show answer and explanation
Answer: D. The matching shown in choice 4 of the Q1 paper
Electromagnetic wavelength decreases from radio/microwave through infrared and visible to ultraviolet, X-rays and gamma rays.
Electromagnetic wavelength decreases from radio/microwave through infrared and visible to ultraviolet, X-rays and gamma rays. The representative orders must follow that sequence. The combination in the fourth Q1 choice is the consistent one.
NEET 2022 · Question 2
Four pressure-volume paths connect the same initial and final volumes. Which path represents the adiabatic process?
- A.Curve 1
- B.Curve 2
- C.Curve 3
- D.Curve 4
Show answer and explanation
Answer: B. Curve 2
For an ideal gas, an adiabatic curve is steeper than the corresponding isothermal curve on a P-V diagram.
For an ideal gas, an adiabatic curve is steeper than the corresponding isothermal curve on a P-V diagram. Comparing the slopes in the original figure identifies curve 2. Hence the second choice is correct.
NEET 2022 · Question 3
A flywheel's angular speed increases uniformly from 1200 rpm to 3120 rpm in 16 s. Find its angular acceleration.
- A.2π rad s⁻²
- B.4π rad s⁻²
- C.8π rad s⁻²
- D.12π rad s⁻²
Show answer and explanation
Answer: B. 4π rad s⁻²
Convert rpm to rad/s and use α=(ω₂−ω₁)/t.
Convert rpm to rad/s and use α=(ω₂−ω₁)/t. The change is 1920 rpm=64π rad/s, and dividing by 16 s gives 4π rad s⁻². Thus option 2.
Chemistry — NEET 2022 sample questions
NEET 2022 · Question 51
Among four P-V process curves shown between comparable states, which represents the greatest work done by the gas?
- A.Curve 1
- B.Curve 2
- C.Curve 3
- D.Curve 4
Show answer and explanation
Answer: B. Curve 2
Work in a quasi-static P-V process equals the area under the curve.
Work in a quasi-static P-V process equals the area under the curve. The second curve encloses the greatest area over the stated volume interval. Therefore option 2.
NEET 2022 · Question 52
Assertion: ICl is more reactive than I₂. Reason: the I–Cl bond is weaker than the I–I bond in this comparison.
- A.Both true and R explains A
- B.Both true but R not explanation
- C.A true, R false
- D.A false, R true
Show answer and explanation
Answer: A. Both true and R explains A
Interhalogen compounds are generally more reactive because the heteronuclear bond is relatively weak/polar.
Interhalogen compounds are generally more reactive because the heteronuclear bond is relatively weak/polar. In this case the bond argument accounts for ICl's greater reactivity. Both statements are true and the reason explains the assertion, option 1.
NEET 2022 · Question 53
Four cyclic conjugated structures are shown. Which one is non-aromatic?
- A.Structure 1
- B.Structure 2
- C.Structure 3
- D.Structure 4
Show answer and explanation
Answer: D. Structure 4
Aromaticity requires a cyclic, planar, continuously conjugated system containing 4n+2 π electrons.
Aromaticity requires a cyclic, planar, continuously conjugated system containing 4n+2 π electrons. Applying Hückel's rule to the displayed structures excludes the fourth one. Therefore option 4.
Botany — NEET 2022 sample questions
NEET 2022 · Question 101
Which is NOT an ex-situ conservation method?
- A.In-vitro fertilisation
- B.National park
- C.Micropropagation
- D.Cryopreservation
Show answer and explanation
Answer: B. National park
National parks conserve organisms within their natural ecosystems and are therefore in-situ conservation.
National parks conserve organisms within their natural ecosystems and are therefore in-situ conservation. IVF, micropropagation and cryopreservation are off-site/ex-situ approaches. Hence option 2.
NEET 2022 · Question 102
Which set of plant-modification statements is correct: cucumber/pumpkin tendrils, Opuntia phylloclade, Rhizophora pneumatophores, grass/strawberry runners, and Citrus/Bougainvillea thorns?
- A.b and c only
- B.a and d only
- C.b,c,d,e only
- D.a,b,d,e only
Show answer and explanation
Answer: C. b,c,d,e only
Cucumber and pumpkin have axillary tendrils, Opuntia has a photosynthetic flattened stem, Rhizophora develops upward pneumatophores and runners aid vegetative propagation.
Cucumber and pumpkin have axillary tendrils, Opuntia has a photosynthetic flattened stem, Rhizophora develops upward pneumatophores and runners aid vegetative propagation. The source's statement about leaflets becoming thorns in Citrus/Bougainvillea is incorrect because the thorns are modified axillary buds. Thus option 3.
NEET 2022 · Question 103
Statement I: Decomposition converts detritus to simpler substances through decomposers. Statement II: Lignin- and chitin-rich detritus decomposes faster.
- A.Both true
- B.Both false
- C.I true, II false
- D.I false, II true
Show answer and explanation
Answer: C. I true, II false
Microbial decomposers break down detritus, so statement I is correct.
Microbial decomposers break down detritus, so statement I is correct. Lignin and chitin resist degradation and slow decomposition rather than accelerate it. Therefore statement II is false and option 3 is correct.
Zoology — NEET 2022 sample questions
NEET 2022 · Question 151
What does in-situ conservation mean?
- A.Protecting the whole ecosystem in its natural habitat
- B.Conserving only high-risk species
- C.Conserving only endangered species
- D.Conserving extinct species
Show answer and explanation
Answer: A. Protecting the whole ecosystem in its natural habitat
In-situ means on-site protection of habitats/ecosystems so populations and ecological interactions are conserved together.
In-situ means on-site protection of habitats/ecosystems so populations and ecological interactions are conserved together. This protects biodiversity at multiple levels. Option 1.
NEET 2022 · Question 152
Which group consists entirely of animals whose digestive tract contains additional chambers such as crop and gizzard?
- A.Crow, pigeon, chameleon
- B.Toad, whale, krait
- C.Catla, pigeon, crocodile
- D.Peacock, parrot, crow
Show answer and explanation
Answer: D. Peacock, parrot, crow
Crop and gizzard are characteristic modifications of the avian alimentary canal.
Crop and gizzard are characteristic modifications of the avian alimentary canal. Peacock, parrot and crow are all birds, whereas the other sets include reptiles, fish, amphibian or mammal. Option 4.
NEET 2022 · Question 153
A DNA molecule is 1.1 m long. Approximately how many base pairs does it contain, using 0.34 nm per base pair?
- A.≈3.3×10⁹ bp
- B.≈6.6×10⁹ bp
- C.≈3.3×10⁶ bp
- D.≈6.6×10⁶ bp
Show answer and explanation
Answer: A. ≈3.3×10⁹ bp
Number of base pairs=L/(0.34×10⁻⁹ m).
Number of base pairs=L/(0.34×10⁻⁹ m). For 1.1 m this is about 3.2×10⁹, conventionally rounded to 3.3×10⁹ bp. Option 1.
