JEE MAIN - Chemistry (2022 - 25th June Evening Shift - No. 17)
Amongst BeF2, BF3, H2O, NH3, CCl4 and HCl, the number of molecules with non-zero net dipole moment is ____________.
Answer
3
Explanation
$\mathrm{BeF}_2, \mathrm{BF}_3$ and $\mathrm{CCl}_4 \Rightarrow \mu_{\mathrm{net}}=0$
$\mathrm{H}_2 \mathrm{O}, \mathrm{NH}_3$ and $\mathrm{HCl} \Rightarrow \mu_{\mathrm{net}} \neq 0$
$\mathrm{H}_2 \mathrm{O}, \mathrm{NH}_3$ and $\mathrm{HCl} \Rightarrow \mu_{\mathrm{net}} \neq 0$
