Given below are two statements:
Statement I: Wet cotton clothes made of cellulose based carbohydrate takes 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 above statements, choose the correct answer from the options given below
Both Statement I and Statement II are true
Statement I is false but Statement II is true
Statement I is true but Statement II is false
Both Statement I and Statement II are false
Statement I is true but Statement II is false.
Solution
Statement I Analysis:
Cotton, composed of cellulose, possesses numerous –OH groups. These groups establish robust hydrogen bonds with water, enabling cotton to absorb significant moisture. Consequently, wet cotton requires a longer drying period compared to nylon, which exhibits lower water absorption.
Statement I is true.
Statement II Analysis:
Nylon incorporates amide groups capable of forming hydrogen bonds with water. However, the overall water absorption capacity of nylon remains considerably lower than that of cotton. In cotton, the extensive presence of –OH groups facilitates substantial hydrogen bonding with water. Therefore, the assertion that nylon exhibits greater intermolecular hydrogen bonding with water than cotton is inaccurate.
Statement II is false.
