What is the number of moles of ' $\mathrm{C}$ ' atoms present in $\mathrm{n}$ mole molecule of alkane if it exhibits three structural isomers?
$3 \mathrm{n}$
$4 \mathrm{n}$
$5 \mathrm{n}$
$6 \mathrm{n}$
Solution
Pentane $\left(\mathrm{C}_5 \mathrm{H}_{12}\right)$ exists in three isomeric forms:
$\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{CH}_2-\mathrm{CH}_2-\mathrm{CH}_3$
