Question

“Keerthi thinks that substitution reactions occur in saturated hydrocarbons; on the contrary, Krishi thinks it occur in unsaturated hydrocarbons.” Justify with valid reasoning whose thinking is correct.

Answer 1

Keerthi’s thinking is correct. Substitution reactions occur in saturated hydrocarbons, where hydrogen atoms are replaced with heteroatoms. In unsaturated hydrocarbons, an addition reaction occurs, where simple molecules are added across double and/or triple bonds.
