Question

multiple choice question
which best describes what occurs in a condensation reaction?
a water molecule is removed from a molecule when it creates a covalent bond.
a covalent bond is broken by adding an oh to one side of the molecule, and an h to the other side.
a bicarbonate group is exchanged for an anion like chlorine.
electrons are removed from a molecule and energy is released.

Explanation:

A condensation reaction involves the formation of a covalent bond between two molecules with the elimination of a water molecule. The other options describe different chemical - change processes such as hydrolysis (adding OH and H to break a bond), ion - exchange, and oxidation (removing electrons).

Answer:

A. A water molecule is removed from a molecule when it creates a covalent bond.
