Interpretation Introduction

(a)

Interpretation: The bond angles in the given compound are to be predicted with the help of its given Lewis structure.

Concept introduction: The geometry and hybridisation of an atom is determined by the number of groups around it. If the number of groups attached to an atom is $2$, then the geometry will be linear. If the number of groups attached to an atom is $3$, then the geometry will be trigonal planar. If the number of groups attached to an atom is $4$, then the geometry will be tetrahedral.
