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
Solution
<p><b>The correct choice is Option D: Statement I is true but Statement II is false.</b></p>
<p><b>Statement I (True)</b></p>
<p>Cotton is made from cellulose, which is a kind of carbohydrate. Cellulose has many –OH groups (hydroxyl groups) which can make strong hydrogen bonds with water. Because of this, cotton holds more water and takes more time to dry than nylon.</p>
<p><b>Statement II (False)</b></p>
<p>Nylon is made of polymer chains with only a few special groups (amide –NH and C=O) that can form hydrogen bonds with water. Nylon forms fewer hydrogen bonds with water compared to cotton. So, cotton actually makes more hydrogen bonds with water than nylon does.</p>
