use the following information to answer the next question.

when this compound reacts with an organic compound having a hydroxyl group, in the presence of acidic medium, such a reaction is a/an
a) elimination reaction
b) addition reaction
c) substitution reaction
d) oxidation reaction
e) condensation reaction

Explanation:

The compound shown is a carboxylic acid (it has a -COOH group). When a carboxylic acid reacts with an alcohol (an organic compound with a hydroxyl -OH group) in an acidic medium, they form an ester and water. This is a condensation reaction (also known as an esterification reaction). In a condensation reaction, two molecules combine to form a larger molecule with the loss of a small molecule (in this case, water).

• Elimination reaction: Removes atoms from a molecule to form a double bond.
• Addition reaction: Adds atoms to a molecule (usually across a double bond).
• Substitution reaction: Replaces one atom or group with another.
• Oxidation reaction: Involves the loss of electrons or an increase in oxidation state.

Answer:

e) condensation reaction
