Number of compounds / species from the following with non-zero dipole moment is ______ \(\mathrm{BeCl}_2,…
Number of compounds / species from the following with non-zero dipole moment is ______
\(\mathrm{BeCl}_2, \mathrm{BCl}_3, \mathrm{NF}_3, \mathrm{XeF}_4, \mathrm{CCl}_4, \mathrm{H}_2 \mathrm{O}, \mathrm{H}_2 \mathrm{~S}, \mathrm{HBr}, \mathrm{CO}_2, \mathrm{H}_2, \mathrm{HCl}\)
Solution
Polar molecule: $\mathrm{NF}_3, \mathrm{H}_2 \mathrm{O}, \mathrm{H}_2 \mathrm{~S}, \mathrm{HBr}, \mathrm{HCl}$
$(\mu \neq 0)$ Non Polar molecule: $\mathrm{BeCl}_2, \mathrm{BCl}_3, \mathrm{XeF}_4, \mathrm{CCl}_4, \mathrm{CO}_2, \mathrm{H}_2$ $(\mu-0)$
So answer is 5 .
