Question

Differentiate between the following pairs based on the criteria given:

Unsaturated and Saturated hydrocarbons (type of bond present)

Answer 1

Unsaturated Hydrocarbon	Saturated Hydrocarbon
Unsaturated hydrocarbons are those where carbon atoms self-catenate through double and triple bonds (σ and π bonds).	Saturated hydrocarbons are those where carbon atoms self catenate through a single bond (σ bond).
E.g. \[\begin{array}{cc} \ce{H - C = C - H}\\ \phantom{}|\phantom{....}|\phantom{}\\ \phantom{}\ce{H\phantom{...}H}\phantom{} \end{array}\] \[\begin {array}{cc} \ce{C ≡ C}\\ |\phantom{....}|\\ \ce{H\phantom{...}H} \end{array}\]	E.g. \[\begin{array}{cc} \ce{H\phantom{...}H}\\ |\phantom{....}|\\ \ce{H - C - C - H}\\ |\phantom{....}|\\ \ce{H\phantom{...}H} \end{array}\]
