Important Chemistry Reactions for Class 12: CBSE
Class 12 students can refer to this list of key
organic chemistry reactions to aid their
preparation. It includes essential reactions like
addition, substitution, and elimination, along with
examples such as esterification and alkylation.
Gattermann Reaction:
The Gattermann reaction transforms aromatic compounds into aldehydes using hydrogen
cyanide, hydrogen chloride, and a catalyst (aluminium chloride or zinc chloride).
Sandmeyer Reaction:
Aromatic diazonium salts react with CuCl or CuBr to yield haloarenes (chlorobenzene or
bromobenzene). It's a key step in synthesising various aryl halides from aryl diazonium salts.
, Balz-Schiemann Reaction:
The method of preparing arene-diazonium chloride with fluoroboric acid. In this reaction, the
arene diazonium fluoroborate is precipitated and decomposes to yield aryl fluoride on heating.
Swarts Reaction:
When alkyl chloride is heated with a metallic fluoride like AgF, Hg2F2, or SbF3, alkyl fluorides
are formed.
Finkelstein Reaction:
Alkyl iodides are prepared easily by reacting alkyl chlorides with Nal in dry acetone.
Wurtz Reaction:
