Alkane is obtained from the catalytic hydrogenation of both alkene a and alkene b. the heat of hydrogenation of alkene a is 29.8 kcal/mol, and the heat of hydrogenation of alkene b is 31.4 kcal/mol.

Alkene A is more stable than alkene B

Explanation:

Complete question:

The same alkane is obtained from the catalytic hydrogenation of both alkene A and alkene B. The heat of hydrogenation of alkene A is 29.8 kcal/mol, and the heat of hydrogenation of alkene B is 31.4 kcal/mol. Which alkene is more stable ?

Step 1: Data given

The heat of hydrogenation of alkene A is 29.8 kcal/mol

The heat of hydrogenation of alkene B is 31.4 kcal/mol

Step 2: Which alkene is more stable

The smaller the heat of hydrogenation, the more stable the alkene. This because it releases less heat, and has less energy.

29.8 < 31.4

This means alkene A has a smaller heat of hydrogenation than alkene B

Alkene A is more stable than alkene B
