The dipole moment of o - , m - and p - dichlorobenzene will be in the following decreasing order

Question

The dipole moment of o - , m - and p - dichlorobenzene will be in the following decreasing order (A) o > p > m (B) p > o > m (C) m > o > p (D) o > m > p

Tardigrade Admin · Accepted Answer

Net dipole moment = μ - μ = 0

μ cosθ/2 θ = 60° in ortho compound θ = 120° in meta compound 0 > m > p

Q. The dipole moment of $o -, m -$ and $p -$ dichlorobenzene will be in the following decreasing order

o > p > m

p > o > m

m > o > p

o > m > p

Net dipole moment $= μ - μ = 0$

$μ cos θ /2$
$θ = 6 0^{\circ}$ in ortho compound
$θ = 12 0^{\circ}$ in meta compound
$0 > m > p$
