Outline the following synthesis:
a) 2 – methyl propene -> 2-methyl-2-propanol.
b) 3 –ethylpentene -> carbon dioxide, water and 2-ethylbutanoic acid.
c) 2 methyl-2-pentene -> 2-chloro-2-methylpetane and 3-chloro-2-methylpentane
d) 1-ethylcyclohexene -> 1-ethyl-1-hydroxy-2-chlorocyclohexane, 1-ethyl-1-choro-2-hydroxycyclohexane and 1-ethyl-1,2-dichlorocyclohexane
