Question

Which among the following is not attracted towards a charged plate?

• A. Water
• B. Ammonia
• C. Hydrochloric acid
• D. Bromine

Answer 1

The correct option is D

Bromine

Explanation for Correct option:

In Bromine molecule($Br-Br$), the electronegativity difference is zero between two Br atoms and is a pure covalent molecule, hence, there is no separation of charges into positive and negative. So, it do not attract to the charged plate.
Explanation for Incorrect options:

A)Water($H_{2}O$) is a polar covalent molecule with unequal sharing of electrons and separates into positive and negative charges and attract to the charged plate.

B)Ammonia($N{H}_3$) is a polar covalent molecule with unequal sharing of electrons and separates into positive and negative charges and attract to the charged plate.
C)Hydrochloric acid($H-Cl$) is a polar covalent molecule with unequal sharing of electrons and separates into positive and negative charges and attract to the charged plate.

Hence, D) is the correct option- Bromine do not attract towards the charged plate.
