Hydrocarbons - Result Question 41
####43. The alkene $R-CH=CH_2$ reacts readily with $B_2 H_6$ and formed the product $B$ which on oxidation with alkaline hydrogen peroxides produces
[1995]
(a) $R-CH_2-CHO$
(b) $R-CH_2-CH_2-OH$
(c) $R-\underset{C_3}{C}=O$
(d)
Show Answer
Solution:
$ \begin{matrix} \text{ (b) } 6 R-CH=CH_2 \underset{\text{ Ether, } 0^{\circ} C}{B_2 H_6} 2(RCH_2 CH_2)_3 B \tag{B}\\ \xrightarrow[\text{ (B) }]{H_2 O_2} 6 RCH_2 CH_2 OH+2 H_3 BO_3 . \end{matrix} $
