1.	Why is NF, trigonal pyramidal while BF, is trigonal planar, though bothare tetra atomic molecules?
Answer» In BF3 there are three bond pairs which are shared in between two atoms resulting in the triangular planar structure while in case of NF3 there is sharing of three bond pairs plus one lone pair. Because of the lone pair sharing the structure get distorted and resulting structure is pyramidal.
