Q.  What is the equilibrium distance for Hydrogen atoms?

a. 0.54 Å
b. 0.64 Å
c. 0.74 Å
d. 0.84 Å


ANSWER: See Answer
 
When the interatomic force between two atoms is zero, the distance between them is called as normal or equilibrium distance. The equilibrium distance for Hydrogen atoms is 0.74 Å.
