Question

Match the compounds in list $I$ with their correct values of dipole moment in lest $II$:

List $I$ compound	List $II$ Dipole moment (D)
$1$. $o$-nitrophenol	$\left(A\right)$ $0.05$
$2$. $o$-dichlorobenzene	$\left(B\right)$ $1.00$
$3$. $o$-xylene	$\left(C\right)$ $1.20$

• A. $1-A,2-B,3-C$
• B. $1-B,2-A,3-C$
• C. $1-C,2-A,3-B$
• D. $1-C,2-B,3-A$

Answer 1

The correct option is D $1-C,2-B,3-A$

O-nitrophenol will bw having the highest dipole moment due to $-R$ effect. Then $\theta -$ dichlorobenzene will be having more dipole moment than $\theta -$ xylene due to the high electronegativity of chlorine.

So, $\theta -$nitrophenol-$1.20D$

$\theta -$dichlorobenzene$-1.00D$

and $\theta -$ xylene$-0.05D$
