QJEEM03Ch6465: JEE Main 2003 Chemistry - Class 11 JEEM03Ch6465 Solution: Which one of the following pairs of molecules will have…

Here $\mu$ _total = $\mu$ ₁ + $\mu$ ₂ $\ne$ 0

$\mu$ _total = $\mu$ ₁ $-$ $\mu$ ₂ = 0

$\mu$ _total = $\mu$ ₁ + $\mu$ ₂ $\ne$ 0

$\mu$ ₁ + $\mu$ ₂ + $\mu$ ₃ = $\mu$ ₄

    $\mu$ _total = 0

In NO₂ and O₃ have permanent dipole moment as both of them are not symmetric molecule.

In CO₂ and SiF₄ each individual bond c = O and S- $-$ F have dipole moment but because of symmetric structure individual dipole moment get's cancelled.
