4. Find the molecule with the maximum dipole moment (a) CH4 (b) NH3 (c) CO2 (d) NF3
The correct option is: c NH3 Explanation:in 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 ...
