Chapter 21.1, Problem 4SSC

Interpretation Introduction

Interpretation:

Saturated and unsaturated hydrocarbons needs to be compared.

Concept introduction:

Compounds that contains only carbon and hydrogen atoms are said to be hydrocarbons. The hydrocarbons can be saturated or unsaturated classified on the basis of the type of bond present in the compound.

Explanation of Solution

The hydrocarbon compounds that contains single bond(s) between carbon atom(s) are said to be saturated hydrocarbon whereashydrocarbon compounds that containsmultiple bond(s) between carbon atom(s) are said to be unsaturated hydrocarbon. Compounds containing single bonds are said to be alkane and compounds containing double bonds are said to be alkene whereas compounds containing triple bonds are said to be alkyne.

For example:

Since, the compound contains only single bonds so, it is an alkane (saturated hydrocarbon).

Since, the compound contains double bond between two carbon atoms so, it is an alkene (unsaturated hydrocarbon).

Since, the compound contains triple bond between two carbon atoms so, it is an alkyne (unsaturated hydrocarbon).
