Which of the following changes in the respectively bond `N_(2) and F_(2)` molecules ?

A

decrease by 0.5 in both

B

increase by 0.5 in both

C

increase by 0.5 in the former and decrease by 0.5 in the later

D

decrease by 0.5 in the frmer and increase by 0.5 in the later

Text Solution

Verified by Experts

The correct Answer is:
D
`underset((3.0))(N_(2))overset(-e^(-))tounderset((2.5))(N_(2)^(+))` (decrease in BO)
`underset((1))(F_(2))overset(-e^(-))tounderset((1.5))(F^(+))` (increase in BO)
