Vedclass · Answer

(D) The dipole moment $\mu$ (observed) is greater than $\mu$ (theoretical) when the bond angle between the polar bonds decreases due to factors like intramolecular hydrogen bonding. In $o$-chlorophenol,the presence of intramolecular hydrogen bonding between the $-OH$ group and the $-Cl$ atom pulls the groups closer,reducing the bond angle between the $C-O$ and $C-Cl$ bonds to less than $60^\circ$. Since $\mu = \sqrt{\mu_1^2 + \mu_2^2 + 2\mu_1\mu_2 \cos 	heta}$,a decrease in the angle $	heta$ leads to an increase in the resultant dipole moment. Therefore,$\mu$ (observed) > $\mu$ (theoretical) for $o$-chlorophenol.

In which of the following molecules is $\mu$ (observed) found to be greater than $\mu$ (theoretical)?
