Assertion : NF(3) has tendency to act as...

Assertion : `NF_(3)` has tendency to act as a donor molecule.
Reason : The highly electronegative F atoms atract electron and these moments partly cancel the moment from the lone pair.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
a


Bond dipole of `N- F` bonds are counter balanced to some extent by the dipole moment of lone pair of electron acting in opposite direction.This reduces the dipole moment and its donor power.
