Some sample questions from NEET 2018 question paper

1. Carboxylic acids have higher boiling points than aldehydes, ketones and even alcohols of comparable molecular mass. It is due to their
(1) More extensive association of carboxylic acid via van der Waals force of attraction
(2) Formation of carboxylate ion
(3) Formation of intramolecular H-bonding
(4) Formation of intermolecular H-bonding
 
Nitration of aniline in strong acidic medium also gives m-nitroaniline because
(1) In absence of substituents nitro group always goes to m-position.
(2) In electrophilic substitution reactions amino group is meta directive.
(3) Inspite of substituents nitro group always goes to only m-position.
(4) In acidic (strong) medium aniline is present as anilinium ion.
 
2. Regarding cross-linked or network polymers, which of the following statements is incorrect?
(1) Examples are bakelite and melamine.
(2) They are formed from bi- and tri-functional monomers.
(3) They contain covalent bonds between various linear polymer chains.
(4) They contain strong covalents bonds in their polymer chains.

3. Oxygen is not produced during photosynthesis by
(1) Cycas
(2) Nostoc
(3) Green sulphur bacteria
(4) Chara
 
4. Double fertilization is
(1) Fusion of two male gametes with one egg
(2) Fusion of one male gamete with two polar nuclei
(3) Fusion of two male gametes of a pollen tube with two different eggs
(4) Syngamy and triple fusion
 
5. Select the correct statement
(1) Spliceosomes take part in translation
(2) Punnett square was developed by a British scientist
(3) Franklin Stahl coined the term ‘‘linkage’’
(4) Transduction was discovered by S. Altman
 
6. Which of the following is not a product of light reaction of photosynthesis?
(1) NADPH
(2) NADH
(3) ATP
(4) Oxygen
 
7. An astronomical refracting telescope will have large angular magnification and high angular resolution, when it has an objective lens of
(1) Large focal length and large diameter
(2) Large focal length and small diameter
(3) Small focal length and large diameter
(4) Small focal length and small diameter
 
8. In a p-n junction diode, change in temperature due to heating
(1) Does not affect resistance of p-n junction
(2) Affects only forward resistance
(3) Affects only reverse resistance
(4) Affects the overall V - I characteristics of p-n junction
 
9. An electron falls from rest through a vertical distance h in a uniform and vertically upward directed electric field E. The direction of electric field is now reversed, keeping its magnitude the same. A proton is allowed to fall from rest in it through the same vertical distance h. The time of fall of the electron, in comparison to the time of fall of the proton is
(1) 10 times greater
(2) 5 times greater
(3) Smaller
(4) Equal
