Question 1
4 / -1

Which is the least reactive halide in both E1 and S_N1 reaction?

A

B

C

D

Solution

Carbocation at bridge head carbon of bicycle compound is highly unstable due to lack of planarity.
Question 2
4 / -1

Reaction intermediate of E1cB reaction is:

A
Carbocation

B
Carbanion

C
Benzyne

D
Free radical

Solution

E1cB take place by carbanian.
Question 3
4 / -1

Benzyne intermediate is not observed in

A

B

C

D

Solution

When aryIhalides having no hydrogen ortho to the halogen do not form benzyne intermediate.
Question 4
4 / -1

A

B

C

D

Solution
Question 5
4 / -1

The final product of the following reaction is:

A

B

C

D

Solution

[-M effect of NO₂ group at ortho and para position]
Question 6
4 / -1

Identify product in the following reaction?

A

B

C

D

Solution
Question 7
4 / -1

The reaction gives the following major product

A

B

C

D

Solution

−CH₃Being an activating group decides the position of incoming electrophile, so, E⁺ adds at position ortho to it as para is blocked.
Question 8
4 / -1

A

B

C

D

Solution

[-M effect of -NO₂ group is at para position]
Question 9
4 / -1

The major product of the following reaction is

A

B

C

D

Solution

The product (1) will be formed. Nucleophilic substitution of an alkyl halide is easier as compared to that of an aryl halide.

Ph^S−is a strong nucleophile and dimethyl formamide is a highly polar aprotic solvent. These reagent favour S_N2 reaction, the major product formed is inversion product.
Question 10
4 / -1

What is the major product obtained in the following reaction?

A

B

C

D

Solution

Because aromatic halides do not give SN reaction in normal condition.
