The decrease in entropy (the $\Delta$S value is negative) observed for alkene addition reactions results from _______.
A) the breaking of a π and $\sigma$ bond.
B) the formation of two $\sigma$ bonds.
C) the reaction being exothermic.
D) two molecules reacting to form a single molecule.
E) the temperature dependence of the $\Delta$S term.

Question

Quizplus · Accepted Answer

In alkene addition reactions, two molecules combine to form a single molecule, which decreases the disorder or randomness, resulting in a negative change in entropy.
