A
X = Ph ––O¹⁸–CH₃ (Trans esterification)

B
X = Ph––O¹⁸–CH₃(esterification reaction)

C
X = Ph––O¹⁸–CH₃(Saponification)

Question 10
1 / -0

Which of the following is the least soluble in water?

A
n-Butyl alcohol

B
n-Heptyl alcohol

C
n-Pentyl alcohol

D
n-Hexyl alcohol

Solution

As the size of the alkyl group becomes larger, it prevents the formation of hydrogen bonds with water molecules and hence the solubility goes on decreasing with the increase in the size or mass of the compound.
Question 11
1 / -0

Which of the following compound reduces by DIBAL-H ?

A
CH₃––OH

B

C
CH₃––O–Et

D
All

Solution

The correct answer is option D
At ordinary temperatures, DIBAL-H reduces a variety of carbonyl compounds, like aldehydes, ketones, carboxylic acids and esters, to corresponding alcohols. These reductions are chemoselective as well as stereospecific.
Question 12
1 / -0

Which of the following compound reduces by NaBH₄ ?

A

B
CH₃–NO₂

C

D

Solution

NaBH₄ are weak reducing agent so only acid chloride are reduced in alcohal.

B
EtOH

C
H₂C=CH₂

D
All

Solution

are not react with NaOH.
