Amines

Question 1

nitrobenzene with H2/Pd or Fe/HCl or Sn/HCl gives

Answer 1

aniline

ntribenezene gets reduced to aniline

Question 2

why is the reaction of nitrobenzene to aniline preferred with Fe/HCl

Answer 2

because FeCl2 formed get hydrolyzed to release hydrochloric acid during the reaction thus only a small amount of hydrochloric acid is required to initiate the reaction

Question 3

Nitrilesd gets reduced to _______by LiAlH4 and H2/Pd

Answer 3

primary amine

Question 4

amides are reduced to ____ by LiAlH4

Answer 4

Primary amines

Question 5

whats formed when ammonia is reacted with a alkyl halide and what is the end product after multiple such process and how to get amine from that and which type of amine is formed?

Answer 5

ammonia with alkyl Halide forms R-NH3X –> R-NH2
this keeps on going till R4NX

amine can be obtained by treating R-NH3X with NaOH resulting in R-NH2

Question 6

Whats Gabriel Phtalimide synthesis

Answer 6

Question 7

write the hoffmann bromamide degradation reaction

Answer 7

Question 8

why are amines more soluble in alcohol ether and benzene

Answer 8

because they are more polar than amines and form stronger intermolecular hydrogen bonds than amines

Question 9

boiling point comparision in primary,secondary and tertiary Amines

Answer 9

Primary>Secondary>Tertiary

Question 10

aniline with K2Cr2O7 forms?

Answer 10

Question 11

the intermoleceluar association in primary amines is less or more than the intermolecular association in secondary amines

Answer 11

less

Question 12

Answer 12

Question 13

R-CN with DIBAL-H forms?

Answer 13

R-CHO

Question 14

phenyl cyanide with SnCl2+HCl forms?

Answer 14

Question 15

wat a semicarbazone moleculue of acetone

Answer 15

Question 16

why does aniline doesn’t gives friedal craft alkylation reaction?

Answer 16

because aniline does a acid-base reaction and forms a bond with AlCl3 which makes the benzene ring highly deactivated

Question 17

amide with LiAlH4 forms!?

Answer 17

Question 18

in the reaction of hypobromite with amide, the carbonyl carbon is lost as

Answer 18

CO3 ^2-

Question 19

chlorobenzene forms the maximum/minimum yield in friedal alkylation reaction

Answer 24

maximum

Question 25

Answer 25

Question 26

reactivity towards reaction with alkyl halides depends on!
