Question

Consider the following molecules and statements related to them :

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

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

(c) (B) dissolves more readily than (A) in water Identify the correct option from below : 

(1) only (a) is true 

(2) (a) and (c) are true 

(3) (b) and (c) are true 

(4) (a) and (b) are true

Answer 1

(3) (b) and (c) are true

(a) B will be more crystalline due to more inter molecular interactions hence more efficient packing. 

(b) B will have higher boiling point due to higher intermolecular interactions.

(c) B will be more soluble in water than A as B will have more extent of H-bonding in water 

So all three statements are correct 

{Solubility date ⇒ O-salicylic acid = 2g/L 

P-salicylic acid = 5g/L}
