Weekly Quiz Competition

Question 1
1 / -0

Statement-1 : In order to converted R−CI to pure R−NH2, Gabriel-phthalimide synthesis can be used.

Statement-2 : With proper choice of alkyl halides, phthalimide synthesis can be used to prepare 1°, 2° or 3° amines.

A
Both Statement-1 and Statement-2 are true and Statement-2 is the correct explanations of Statement-1.

B
Both Statement-1 and Statement-2 are true and Statement-2 is not the correct explanation of Statement-1.

C
Statement-1 is true but Statement-2 is false.

D
Statement-1 is false but Statement-2 is true.

Solution

Only primary aliphatic amines can be prepared by Gabriel phthalimide reaction.

The correct answer is: Statement-1 is true but Statement-2 is false
Question 2
1 / -0

Nitrobenzene can be reduced to aniline by

H₂/Ni Sn/HCI Zn/NaOH LiAIH₄

I II III IV

A
I, II and IV

B
I and I

C
I, II and III

D
only II

Solution

LiAIH₄ does not reduce −NO₂ group to −NH₂ group.

The correct answer is: I, II and IV
Question 3
1 / -0

Statement-1 : 1° Amides react with Br₂+NaOH to give 1° amines with one carbon atom less than the parent amide.

Statement-2 : The reaction occurs through intermediate formation of acylnitrene.

A
Both Statement-1 and Statement-2 are true and Statement-2 is the correct explanations of Statement-1.

B
Both Statement-1 and Statement-2 are true and Statement-2 is not the correct explanation of Statement-1.

C
Statement-1 is true but Statement-2 is false.

D
Statement-1 is false but Statement-2 is true.

Solution

Reason is the correct explanation of Assertion.

The correct answer is: Statement-1 is true but Statement-2 is false.
Question 4
1 / -0

The correct order of basic character of the following amines in chlorobenzene is.

Ethyl amine, Diethyl amine and Tri ethyl amine

A
(C₂H)₅₃N<C₂H₅NH₂<(C₂H₅)₂N.

B
C₂H₅NH₂<(C₂H₅)₃N<(C₂H₅)₂NH.

C
C₂H₅NH₂<(C₂H₅)₂NH<(C₂H₅)₃N.

D
(C₂H₅)₃N<(C₂H₅)₂N<C₂H₅NH₂

Solution

In presence of chloro benzene, hydrogen bonding is not possible between the protonated amine and the solvent and thus the stabilization factor (salvation effect) is absent. Hence basicity is explained on the basis of the number of electron releasing groups in an amine.

The correct answer is: xC₂H₅NH₂<(C₂H₅)₂NH<(C₂H₅)₃N.
Question 5
1 / -0

Find the main product for the following reaction.

Reaction: Aniline is treated with acetyl chloride in presence of anhydrous aluminium chloride.

A
O - aminoacetophenone

B
p-aminoacetophenone

C
both (a) and (b)

D
m-aminoacetophenone

Solution

In presence of AICI₃ (a Lewis acid), aniline is converted into anilinium cation, which being m-directing gives m-amino aceto- phenone.

The correct answer is: m-aminoacetophenone
Question 6
1 / -0

Statement-1: Sulphanilic acid exists as a dipolar ion whereas

p-aminobenzoic acid does not.

Statement-2 : Carboxyl group, being more acidic than −SO3H group, can easily transfer a H⁺ to the amino group.

A
Both Statement-1 and Statement-2 are true and Statement-2 is the correct explanations of Statement-1.

B
Both Statement-1 and Statement-2 are true and Statement-2 is not the correct explanation of Statement-1.

C
Statement-1 is true but Statement-2 is false.

D
Statement-1 is false but Statement-2 is true.

Solution

SO₃H group, being more acidic than −CO₂H group, can easily transfer a proton to the amino group.

The correct answer is: Statement-1 is true but Statement-2 is false.
