7. Answer the following
i. HCl is added to a hydrocarbon ‘A’ (C4H8) to give a compound ‘B’ which on hydrolysis with aqueous alkali forms tertiary alcohol ‘C’ (C4H10O). Identify ‘A’ , ‘B’ and ‘C’.
\[ \begin{array}{cc} \ce{CH3}\phantom{..............................}\ce{CH3}\phantom{.............................}\ce{CH3}\phantom{}\\ |\phantom{..................................}|\phantom{.................................}|\\ \ce{\underset{\text{2-Methylprop-1-ene}}{H3C - C = CH2} + HCl ->[Markovnikov][rule] H3C - C - CH3->[KOH(aq.)
