NEET Chemistry Previous Year Question Paper with Solutions

Candidates can check the NEET UG Chemistry previous year questions along with their solutions for practice below. Use these questions for honing your skill in Physical, Inorganic and Organic Chemistry.

Q) Gadolinium has a low value of third ionisation enthalpy because of
(1) small size
(2) high exchange enthalpy
(3) high electronegativity
(4) high basic character

Answer (2)
Sol. Electronic configuration of Gadolinium
Gd :— [Xe] 4f7 5d1 6s2
In case of 3rd ionisation enthalpy electron will be removed from 5d and resultant configuration will be [Xe]4f7, that is stable electronic configuration as it will have high exchange energy, hence less energy will be required to remove 3rd electron.

Q) Given below are two statements :
Statement I : The boiling points of aldehydes and ketones are higher than hydrocarbons of comparable molecular masses because of weak molecular association in aldehydes and ketones due to dipole – dipole interactions.
Statement II : The boiling points of aldehydes and ketones are lower than the alcohols of similar molecular masses due to the absence of H-bonding.
In the light of the above statements, choose the most appropriate answer from the given below
(1) Both Statement I and Statement II are correct
(2) Both Statement I and Statement II are incorrect
(3) Statement I is correct but Statement II is incorrect
(4) Statement I is incorrect but Statement II is correct
Answer (1)

Sol. • The boiling points of aldehydes and ketones are higher than hydrocarbons of comparable molecular masses due to weak molecular association in aldehydes and ketones arising out of the dipole – dipole interaction.
• Alcohols involved intermolecular hydrogen bonding, because of which the boiling point of aldehydes and ketones are lower than the alcohols of similar molecular masses.

Q) The incorrect statement regarding chirality is
(1) SN1 reaction yields 1 : 1 mixture of both enantiomers
(2) The product obtained by SN2 reaction of haloalkane having chirality at the reactive site shows inversion of configuration
(3) Enantiomers are superimposable mirror images on each other
(4) A racemic mixture shows zero optical rotation

Answer (3)
Sol. The stereoisomers related to each other as non-superimposable mirror image are called enantiomers.

Q) In one molal solution that contains 0.5 mole of a solute, there is
(1) 500 mL of solvent (2) 500 g of solvent
(3) 100 mL of solvent (4) 1000 g of solvent

Answer (2)
Sol. Molality is the moles of solute dissolved per kg of solvent therefore 500 g, 1 molal solution contains
0.5 of solute, as

m = Moles of solute/Mass of solvent (in kg)
1 = 0.5/Mass of solvent (in kg)
Mass of solvent (in kg) = 0.5
= 500 g

Q) A 10.0 L flask contains 64 g of oxygen at 27ºC. (Assume O2 gas is behaving ideally). The pressure inside the flask in bar is (Given R = 0.0831 L bar K–1 mol–1)
(1) 2.5 (2) 498.6
(3) 49.8 (4) 4.9

Answer (4)
Sol. We know for ideal gas

PV = nRT
P = nRT/V

P = (64/32) x (0.0831 x 300)/10
P = 4.9 bar
Pressure of O2 gas inside the flask = 4.9 bar
