How to Calculate Index of Hydrogen Deficiency (IHD) or Degree of Unsaturation

Degree of unsaturation also known as Index of hydrogen deficiency (IHD) is number of pi bond or ring present in the structure of organic molecule. This value helps to elucidate structure of unknown molecules. 

Key words: Molecular formula, Index of hydrogen deficiency (IHD), Structure analysis.

In this article we will learn about calculation of degree of unsaturation in organic chemistry.
