Question

$N{H}_3$ has dipole moment but $S{F}_6$ doesn't.
If true enter 1, else enter 0.

Answer 1

The $N{H}_3$ molecule has a dipole moment because the three $N-H$ bond dipoles add to give a net dipole pointing upward to the $N{H}_3$ structure. The $S{F}_6$ molecule has no dipole moment because each $S-F$ bond dipole is balanced by one of equal magnitude pointing in opposite direction of the other side of the molecule.
