Index of Hydrogen Deficiency (continued)

Slide 16 of 39

Notes:

Examples of Application of Index

1. Given the number of carbons in the hydrocarbon and the Index of Hydrogen Deficiency, determine the molecular formula

Example: What is the molecular formula of an eight carbon hydrocarbon with an Index of 3?

2. Given the number of carbons in the hydrocarbon and the Index, speculate on what kind of hydrocarbon it is in terms of unsaturation.

Example:Speculate on the possible structure of a hydrocarbon of 6 carbons and an index of 2.
