Hydroquinone (benzene$-1,4-$diol)

Vedclass · Answer

(A) molecule is polar if its net dipole moment $(\mu)$ is non-zero. $1$. Hydroquinone (benzene$-1,4-$diol): The two $-OH$ groups are at the para position. Due to the rotation of the $-OH$ bonds,the dipole moments do not cancel out completely,resulting in a net dipole moment $(\mu 
eq 0)$. Thus,it is polar. $2$. $1,4-$dichlorobenzene: This is a symmetric molecule where the dipole moments of the two $C-Cl$ bonds are equal and opposite,canceling each other out,so $\mu = 0$. $3$. Terephthalonitrile: This is also a symmetric molecule where the dipole moments of the two $C \equiv N$ groups cancel each other out,so $\mu = 0$. Therefore,only hydroquinone is polar.
