Chapter 1, Problem 81CP

(a)

Interpretation Introduction

Interpretation:

To identify the bond angle of the two N-C-N units present in the given compound and to predict why the highlighted regions are in close proximity when adopting three-dimensional shape.

Concept introduction:

The atomic orbitals mix together to form a hybrid orbital which is suitable for forming bonds between the atoms to form a compound.  This mixing of hybrid orbitals is known as hybridization.  The hybridization determines the geometry of the particular atom in the compound.  Shortly to say

$s{p}^{3}hybridized$ =tetrahedral

trigonal pyramidal(if one lone pair of electron is present)

bent geometry (if two lone pair of electrons are present)

$s{p}^{2}hybridized$ =trigonal planar

$sp$ $hybridized$ =linear

To identify: To identify the bond angle of both N-C-N in the given compound
