Interpretation Introduction

(a)

Interpretation:

The condensed structure of an alkane which contains only $1°$ and $2°$ carbons should be drawn.

Concept Introduction:

Compounds consist of carbon and hydrogen is known as hydrocarbons. Hydrocarbons are classified as saturated hydrocarbon and unsaturated hydrocarbon. Saturated hydrocarbons are those hydrocarbons in which carbon-carbon single bond is present as carbon is linked with four atoms. Unsaturated hydrocarbons are those hydrocarbons in which carbon-carbon multiple bonds are present that is double and triple bond.

Saturated hydrocarbon is known as alkane having general molecular formula ${\text{C}}_n{\text{H}}_{2n+2}$.

In organic chemistry, carbons are classified as primary, secondary, tertiary and quaternary carbons.

Primary carbon ( $1°$ ) is defined as the carbon which is bonded to other carbon atom and it is present at the end of chain.

Secondary carbon ( $2°$ ) is defined as the carbon which is bonded to two other carbon atoms.

Tertiary carbon ( $3°$ ) is defined as the carbon which is bonded to other three carbon atoms.

Quaternary carbon ( $4°$ ) is defined as the carbon which is bonded to four other carbon atoms.

Condensed structural formula is defined as the structural formula which shows the spatial arrangement of bonds in an organic compound. In this structural formula, the bonds between the atoms are shown with lines and omit the bond between carbon and hydrogen atoms.

Interpretation Introduction

(b)

Interpretation:

The condensed structure of an alkane with molecular formula ${\text{C}}_{\text{5}}{\text{H}}_{\text{12}}$ has only one $3°$ carbon should be drawn.

Concept Introduction:

Compounds consist of carbon and hydrogen is known as hydrocarbons. Hydrocarbons are classified as saturated hydrocarbon and unsaturated hydrocarbon. Saturated hydrocarbons are those hydrocarbons in which carbon-carbon single bond is present as carbon is linked with four atoms. Unsaturated hydrocarbons are those hydrocarbons in which carbon-carbon multiple bonds are present that is double and triple bond.

Saturated hydrocarbon is known as alkane having general molecular formula ${\text{C}}_n{\text{H}}_{2n+2}$.
