Convert the following structural formulae to bond-line formulae: (a) \(\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}(\mathrm{OH}) \mathrm{CH}_{3}\), (b) \(\left(\mathrm{CH}_{3}\right)_{3} \mathrm{Cl}\) (c) \(\left(\mathrm{CH}_{3} \mathrm{CH}_{2}\right)_{2} \mathrm{C}=\mathrm{O}\) (d) \(\mathrm{CH}_{3} \mathrm{COCH}_{2} \mathrm{COOCH}_{2} \mathrm{CH}_{3}\) (e)

(a) \(\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}(\mathrm{OH}) \mathrm{CH}_{3}\) corresponds to \(\mathrm{H}_{3}\mathrm{C}-\mathrm{CH}_{2}-\mathrm{CH}(\mathrm{OH})-\mathrm{CH}_{3}\) in bond-line formula. (b) \(\left(\mathrm{CH}_{3}\right)_{3} \mathrm{Cl}\) corresponds to \(\mathrm{CH}_{3}\mathrm{Cl}\) surrounded by three \(\mathrm{CH}_3\) groups in bond-line formula. (c) \(\left(\mathrm{CH}_{3} \mathrm{CH}_{2}\right)_{2} \mathrm{C}=\mathrm{O}\) corresponds to two \(\mathrm{CH}_{3}-\mathrm{CH}_{2}\) groups attached to a \(\mathrm{C}=\mathrm{O}\) group in bond-line formula. (d) \(\mathrm{CH}_{3} \mathrm{COCH}_{2} \mathrm{COOCH}_{2} \mathrm{CH}_{3}\) corresponds to \(\mathrm{CH}_{3}-\mathrm{CO}-\mathrm{CH}_{2}-\mathrm{CO}-\mathrm{O}-\mathrm{CH}_{2}-\mathrm{CH}_{3}\) in bond-line formula.
