Consider the following molecular formulae of carbon compounds :
(i)
$\displaystyle \mathrm{CH}_{3} \mathrm{COOH}$
(ii)
$\displaystyle \mathrm{CH}_{3} \mathrm{OH}$
(iii)
$\displaystyle \mathrm{C}_{2} \mathrm{H}_{6}$
(iv)
$\displaystyle \mathrm{C}_{3} \mathrm{H}_{4}$
(v)
$\displaystyle \mathrm{C}_{4} \mathrm{H}_{8}$
(a)
Which one of these compounds belongs to homologous series of alcohols ?
(b)
Identify the compound having triple bond between carbon - carbon atoms.
(c)
Write the molecular formula of the first member of the homologous series to which $\displaystyle \mathrm{CH}_{3} \mathrm{COOH}$ belongs.
(d)
Write the general formula of the series to which the compound $\displaystyle \mathrm{C}_{4} \mathrm{H}_{8}$ belongs.
Marking-scheme solution
(a) \(\displaystyle \mathrm{CH}_{3} \mathrm{OH}\)
