Question

Calculate the dipole moment of m-dicholorobenzene $[\mu =1.5D]$

• A.
• B.
• C.
• D.

Answer 1

The correct option is B

n: Net dipole moment $=\sqrt{{\mu }_1^2+{\mu }_2^2+2{\mu }_1{\mu }_{2}cos\theta }$

In this case $\theta$ = ${120}^{\circ }$ and $\mu =1.5$

$\therefore {\mu }_{meta}=\sqrt{{1.5}^2+{1.5}^2+2(1.5{)}^{2}cos{120}^{\circ }}$

${\mu }_{net}=1.5D$
