NEET Chemistry Atomic Radius MCQ Question
Type: MCQ-numerical-Easy-Class 11
The bond distance in a hydrogen molecule (H2) is 74 pm. What is the covalent radius of a hydrogen atom?
A
37 pm
B
74 pm
C
148 pm
D
92 pm
Correct Answer
Option A
Detailed Explanation
The covalent radius of an atom in a diatomic molecule is half the bond distance. Therefore, for H2, it is 74 pm / 2 = 37 pm.
