Q. Amongst $BeF _{2}, BF _{3}, H _{2} O , NH _{3}, CCl _{4}$ and $HCl$, the number of molecules with non-zero net dipole moment is ____

JEE MainJEE Main 2022Chemical Bonding and Molecular Structure

Solution:

$BeF _{2}, BF _{3}$ and $CCl _{4} \Rightarrow \mu_{\text {net }}=0$
$H _{2} O , NH _{3} \text { and } HCl \Rightarrow \mu_{\text{net }} \neq 0$
