Vedclass · Accepted Answer

$R-CH_2-CH_2-OH$

Vedclass · Answer

(B) The reaction of an alkene with diborane $(B_2H_6)$ followed by oxidation with alkaline hydrogen peroxide $(H_2O_2/OH^-)$ is known as hydroboration-oxidation. This reaction results in the anti-Markovnikov addition of water across the double bond,yielding a primary alcohol. $6R-CH=CH_2 + B_2H_6$ $\rightarrow 2(R-CH_2-CH_2)_3B$ $\xrightarrow{H_2O_2/OH^-} 6R-CH_2-CH_2-OH + 2H_3BO_3$.

The alkene $R-CH=CH_2$ reacts readily with $B_2H_6$ and forms the product $B$,which on oxidation with alkaline hydrogen peroxide produces:
