Isomerization is another term for rearrangement.

• A. Combustion
• B. Polymerization
• C. Rearrangement
• D. Ionization

Answer: (C)

Isomerization is the rearrangement of atoms within a molecule to form a different isomer while keeping the same molecular formula. It focuses on how the same atoms are connected or arranged differently, so you can end up with a different structure or geometry without adding or removing anything from the molecule. A classic idea is shifting bonds or repositioning parts of the molecule to produce a new isomer, like a straight-chain form changing into a branched or cis/trans arrangement. This isn’t combustion, which involves reacting with oxygen and releasing energy to form new substances like carbon dioxide and water; nor is it polymerization, which builds up large polymers from smaller units; nor is it ionization, which creates charged species by removing or adding electrons. These processes change the chemical identity or formula of the species, whereas isomerization changes arrangement within the same formula.
