Question

during a reaction, the -oh group of an alcohol is replaced by a chlorine atom. which type of reaction occurred? addition condensation elimination substitution

Explanation:

In a substitution reaction, one atom or group of atoms in a molecule is replaced by another atom or group of atoms. Here, the -OH group of an alcohol is replaced by a chlorine atom, which is characteristic of a substitution reaction. Addition reactions involve adding atoms to a double - or triple - bond, condensation reactions involve the loss of a small molecule like water during the formation of a new bond, and elimination reactions involve the removal of atoms or groups to form a multiple bond.

Answer:

D. substitution
