Statement I: Wet cotton clothes made of cellulose-based carbohydrate take comparatively longer time to get dried than wet nylon polymer-based clothes. Statement II: Intermolecular hydrogen bonding with water molecule is more in nylon-based clothes than in the case of cotton clothes.

Drying of Cotton vs Nylon Clothes | JEE Main PYQ | Chemical Bonding

Given below are two statements:

Statement I: Wet cotton clothes made of cellulose-based carbohydrate take comparatively longer time to get dried than wet nylon polymer-based clothes.

Statement II: Intermolecular hydrogen bonding with water molecule is more in nylon-based clothes than in the case of cotton clothes.

In the light of the above statements, choose the correct answer from the options given below.

(A) Both Statement I and Statement II are false

(B) Both Statement I and Statement II are true

(D) Statement I is true but Statement II is false

Correct Answer: Statement I is true but Statement II is false

Explanation

Cotton (cellulose) contains a large number of –OH groups which form strong hydrogen bonds with water, so cotton retains water and dries slowly.

Nylon has fewer sites for hydrogen bonding with water compared to cotton, therefore it dries faster.

Hence, Statement I is true and Statement II is false.
