Question

Rank the following isomers from most stable to least stable.

Answer 1

Concepts and reason

The concept used to solve this problem is based on stability of the organic isomers. The isomers are the compounds, which have same structural formula and different spatial arrangements.

Fundamentals

The stability of the molecules can be determined by the number of the substituents present. The carbon, which represents the maximum number of substitution, is the most stable carbon in the compound.

The compound A is more stable than the compound B. The alkene present in the compound B is the least substituted alkene. However, the alkene present in the compound A is more substituted than the compound B.

The compound C is more stable than the compound A. The alkene present in the compound A is the least substituted alkene. The alkene present in the compound C is substituted by the three molecules. Hence, the compound C is the most stable compound.

Ans:

The order of the stability of the compound is as follows.

${\rm{C}} > {\rm{A}} > {\rm{B}}$
