Which out of the two following molecules is trigonal planar shape NF3 or PCL3?

Answer 1

Yes it is. (because of the lone pairs on N)

Answer 2

NF3 has a trigonal planar molecular shape due to its three bonding pairs and one lone pair of electrons around the central nitrogen atom. In contrast, PCl3 has a trigonal pyramidal molecular shape because it has three bonding pairs and one lone pair of electrons around the central phosphorus atom.

Answer 3

Trigonal Pyramidal. It is not trigonal planar because there is one lone pair around the central atom, just like the shape of ammonia.

Answer 4

Neither.

Due to the lone pairs on the N and P atoms, both molecules have a trigonal pyramidal shape.
