b. Structure of Chloropentane

ii. Structure (i) is 2,3-dimethylbutane, whereas Structure (ii) is 2,2-dimethylbutane. Both are isomers of the compound with the chemical formula $\mathrm{C}_{6} \mathrm{H}_{14}$.
iii. Unsaturated carbon compounds always follow the general formula $\mathrm{C}_{\mathrm{n}} \mathrm{H}_{2 \mathrm{n}}$ if there is a carbon-carbon double bond and formula $\mathrm{C}_{\mathrm{n}} \mathrm{H}_{2 \mathrm{n}-2}$ if there is a carbon-carbon triple bond. Saturated carbon compounds always follow the general formula $\mathrm{C}_{\mathrm{n}} \mathrm{H}_{2 \mathrm{n}+2}$.

b. Structure of Chloropentane

ii. Structure (i) is 2,3-dimethylbutane, whereas Structure (ii) is 2,2-dimethylbutane. Both are isomers of the compound with the chemical formula $\mathrm{C}_{6} \mathrm{H}_{14}$.
iii. Unsaturated carbon compounds always follow the general formula $\mathrm{C}_{\mathrm{n}} \mathrm{H}_{2 \mathrm{n}}$ if there is a carbon-carbon double bond and formula $\mathrm{C}_{\mathrm{n}} \mathrm{H}_{2 \mathrm{n}-2}$ if there is a carbon-carbon triple bond. Saturated carbon compounds always follow the general formula $\mathrm{C}_{\mathrm{n}} \mathrm{H}_{2 \mathrm{n}+2}$.
