Interpretation Introduction

Interpretation: For the given reaction, the structures should be drawn for the compound A and B with molecular formula ${\text{C}}_{\text{8}}{\text{H}}_{\text{8}}\text{and}{\text{C}}_{\text{8}}{\text{H}}_{\text{8}}{\text{Br}}_{\text{2}}$ respectively.

Concept introduction:

To draw the chemical structure the degree of unsaturation formula is used.

The formula gives the information about the number of rings, double bonds and triple bonds present in the compound.

$\text{Degree}\text{of}\text{unsaturation}\text{=}\frac{\left[\left(\text{Number}\text{of}\text{carbon×2}\right)\text{+}\left(\text{2-number}\text{of}\text{hudrogen}\right)\right]}{\text{2}}$
