Q.
Which compounds exhibits maximum dipole moment among the following?
NTA AbhyasNTA Abhyas 2020Chemical Bonding and Molecular Structure
Solution:
$-NO_{2}$ group has electron withdrawing nature
$-NH_{2}$ group has electron releasing nature so in para positions $\underset{\mu _{1}}{ \rightarrow }$ and $\underset{\mu _{2}}{ \rightarrow }$ will simply add up to give the maximum value of resultant dipole moment of the molecule $\left(\mu=\mu_1+\mu_2\right)$. .
