Chapter 16.4, Problem 6ATS

Interpretation Introduction

Interpretation: The structure of given molecular formula and the total number of proton signals should be identified.

Concept Introduction:

1H NMR: A technique gives information to predict the Carbon and Hydrogen connectivity in the organic compounds.

HDI (Index of hydrogen deficiency): HDI values gives information on the level of unsaturation (means a double bond or a ring) on the structure of the compound.

$\text{HDI= }\frac{\left(\text{ 2C+2+N-H-X}\right)}{\text{2}}$

$\begin{array}{l}\text{C }\text{indicates}\text{number}\text{of}\text{carbon}\\ \text{N }\text{indicates}\text{number}\text{of}\text{nitrogen}\\ \text{H }\text{indicates}\text{number}\text{of}\text{hydrogen}\\ \text{X }\text{indicates}\text{number}\text{of}\text{halogen}\end{array}$
