Question

If the dipole moment of $C-Cl$ bond is $1.2$ $D$, then the resulting value of dipole moment in:

• A. $1.2$ and $0.6$ respectively
• B. $0.6$ and $1.2$ respectively
• C. Less than $1.2$ $D$ and more than $1.2$ $D$ respectively
• D. More than $1.2$ $D$ in both

Answer 1

The correct option is B $0.6$ and $1.2$ respectively

net dipole moment's magnitude $=\sqrt{(1.2{)}^2+(1.2{)}^2+2(1.2{)}^2\cos \theta }$

$=1.2D$

net dipole moment's magnitude $=\sqrt{(1.2{)}^2+(1.2{)}^2+2(1.2{)}^2\cos \theta }$

$=\left(\sqrt{3}\right)\left(1.2\right)D$
