Question

Consider the following molecules and statements related to them:

(a) (B) is more likely to be crystalline than (A)

(b) (B) has a higher boiling point than (A)

(c) (B) dissolves more readily than (A) in water

Identify the correct option from below:

• A. (a) and (c) is true
• B. Only (a) is true
• C. All are true
• D. (a) and (b) are true

Answer 1

The correct option is C

All are true

The above question can be explained as:

1. Due to the presence of Intramolecular $\mathrm{H}$-Bonding in ortho substituted benzoic acid, it is less likely to be crystalline than para substituted benzoic acid.
2. Due to the absence of intramolecular $\mathrm{H}$-Bonding in para substituted benzoic acid, it has a higher boiling point and dissolves more readily in water than ortho substituted benzoic acid.

Therefore, the above points clearly explains the molecules and statements related to them.
