dipole moment?
TAIPMT-2014]
(1) CO2
(2) CH4
(3) NH3
(4) NF3​

Answer 1

Answer:

The correct option is: ( c ) NH3

Explanation:

NH3 H is less electronegative than N and hence dipoie moment of each N - H bond is towards N and create high net dipole moment whereas in NF3 F is more electronegative than N the dipole moment of each N - F bond is opposite to that of lone pair hence reducing the net dipole moment.

Answer 2

Answer:

4) NF3.
