Question

Molecules containing two carbon atoms and a functional group have many home and industrial uses. these compounds can be produced by a variety of reactions, as shown by

Answer 1

Group of atoms that react to the compounds in a predictable or a desired way is called a functional group. Few of the examples for these varied reactions which produce these compounds are
1: C2H4 + H2O → CH3CH2OH
2: 2CH3CH2OH + O2 → 2CH3CHO + 2H2O
3: 2CH3CHO + O2 → 2CH3COOH
