(a)
Interpretation:
The name of the given shape is to be written.
Concept introduction:
Every molecule has a fixed molecular structure which depends on arrangement of electron pairs around the central atom. VSEPR theory helps to find the structure of a compound using bond pairs and lone pairs counting.

Answer to Problem 9STP
Pyramidal shape
Explanation of Solution
The given shape is:
It is pyramidal shape. The molecule acquires pyramidal shape when central atom has three bond pairs and one lone pair. Presence of lone pair distorts the molecular shape. The given molecule has geometry tetrahedral and shape pyramidal. In it all the bonds are at angle of
