Organic conversion is the conversion of one particular functional group to another functional group present in a chemical compound that is facilitated with the help of a particular organic reagent and solvent.

The organic conversion method is used in the chemical industry for the formation of desired carbon compounds.

(a) Halogenation of Hex-1yne with one mole of chlorine $\left({\text{Cl}}_{\text{2}}\right)$forms 1,2-dichlorohex-1-ene.

Formation of 1,2-dichlorohex-1-ene.

(b) Addition of hydrogen halide HBr in presence of peroxide in Hex-1yne forms 1-bromohex-1-ene.

Formation of 1-bromohex-1-ene.

(c) Addition of one mole of hydrogen halide HBr in Hex-1yne forms 2-bromohex-1-ene.

Formation of 2-bromohex-1-ene

(d) Halogenation of Hex-1yne with two moles of chlorine $\left({\text{Cl}}_{\text{2}}\right)$in presence of ${\text{CCl}}_{\text{4}}$forms 1,1,2,2-tetrabromohexane.

Formation of 1,1,2,2-tetrabromohexane

(e) Hydrogenation of Hex-1yne with Lindlar’s catalyst or treating it with sodium metal in liquid ammonia $\left({\text{Na/NH}}_{\text{3}}\right)$first form hex-1-ene then adding one mole of hydrogen halide HBr in hex-1-ene forms 2-bromohexane.

Formation of 2-bromohexane

(f) Addition of 2 moles of hydrogen halide HBr in Hex-1yne forms 2,2-dibromohexane.

Formation of 2,2-dibromohexane
