Question

Which one of the following molecules is planar? (A) NF3 (B) NCl3 (C) PH3 (D) BF3

Tardigrade Admin · Accepted Answer

BF3 has triangular planar arrangement. There identical vectors acting in outward direction, at equal angles in a plane, cancel each other giving zero resultant, hence non-polar.
