WebIn organic chemistry, a cycloaddition is a chemical reaction in which "two or more unsaturated molecules (or parts of the same molecule) combine with the formation of a cyclic adduct in which there is a net reduction of the bond multiplicity ". The resulting reaction is a cyclization reaction. WebAn elimination reaction is a reaction in which atoms are removed as molecules or compounds. Elimination is generally catalysed by a metal, an acid or base. Elimination reactions often compete with substitution reactions. In this reaction, a substrate (typically an alkyl halide) eliminates one equivalent (unit) of acid to form an alkene. lahrbio https://pckitchen.net
