Rearranging materials may result in all of the following EXCEPT:

• A. Disproportionation
• B. Tautomerization
• C. Polymerization
• D. Isomerization

Answer: (C)

Rearrangement means changing how atoms are connected within a substance without adding new atoms from outside. Disproportionation, tautomerization, and isomerization all involve such internal reorganization of bonds or positions: disproportionation redistributes atoms/electrons between two species to yield different oxidation states; tautomerization involves shifting a proton and moving a double bond within the same molecule; isomerization converts one arrangement of atoms into another with the same molecular formula. Polymerization does not fit this pattern because it builds a larger molecule by linking separate monomer units, forming new bonds between distinct molecules rather than simply reconfiguring bonds within an existing one. So polymerization is the exception.
