Interpretation Introduction

Interpretation:

Number of Π bonds in the given organic compound has to be determined.

Concept introduction:

Molecular formula is a chemical formula that shows the total number of kinds of atoms in a molecule. Some types of organic compounds and their general formulas listed below,
Organic compoundGenaral formulaAlkaneCnH2n+2AlkeneCnH2nAlkyneCnH2n−2

In the formula of organic compound two hydrogen atom should be subtracted from its general formula if the compound contains Π bond or ring.

Degree of unsaturation of an organic compound can be determined by using the equation,

(2n+2−X)2n = number of carbon in the moleculeX = number of hydrogen atom in the molecule

The number of Π bonds can be calculated using the above equation also. Because the presence of Π bonds make the compound unsaturated.
