Interpretation Introduction

Interpretation: The structure of a given molecular formula ${\text{C}}_{\text{5}}{\text{H}}_{\text{12}}$ to be predicted.

Concept Introduction:

HDI: Calculation of Hydrogen deficiency index is to find the level of unsaturation (presence of double bond, triple bond or a ring) in the structure.

$\begin{array}{l}\text{HDI=}\frac{\text{2(C)+2+N-H-X}}{\text{2}}\\ \text{where,}\\ \text{C}\text{represent}\text{number}\text{of}\text{carbon,}\\ \text{N}\text{represent}\text{number}\text{of}\text{nitrogen,}\\ \text{H}\text{represent}\text{number}\text{ofhydrogen,}\\ \text{X}\text{represent}\text{number}\text{ofhalogen}\text{.}\end{array}$.
