Question
Chapter 13, Problem 74E
Interpretation Introduction
Interpretation: All the possible Lewis structure for dimethylborazine needs to be drawn and if there will be different number of structures without resonance or not needs to be determined.
Concept Introduction:
Lewis dot structure is the representation which shows the bonding between atoms present in a molecule. It shows lone pairs and bond pairs that existing on each bonded atom. Lewis dot structure is also known as Lewis dot formula or electron dot structure.
The sum of valence electrons must be arranged in such a way that all atoms must get octet configuration (8 electrons).
