Statement I: Propene on treatment with diborane gives an addition product with the formula ((CH3)2 - CH)3B

Question

Given below are two statements: 

Statement I: Propene on treatment with diborane gives an addition product with the formula \(((CH_3 )_2 - CH )_3 B\)

Statement II: Oxidation of \(((CH_3 )_2 - CH) _3B\) with hydrogen peroxide in presence of NaOH gives propan-2- ol. 

In the light of the above statements, choose the most appropriate answer from the options given below: 

(1) Statement I is correct but Statement II is incorrect 

(2) Statement I is incorrect but Statement II is correct 

(3) Both Statement I and Statement II are correct 

(4) Both Statement I and Statement II are incorrect

Answer 1

Correct option is (2) Statement I is incorrect but Statement II is correct 

\(CH_3 CH = CH_2 + (H - BH_2)_2 \longrightarrow CH_3 - CH_2 - CH_2 - BH_2\)\(\xrightarrow {CH_3 CH=CH_2} (CH_3 - CH _2 - CH _2 )_2 BH\)\(\xrightarrow {CH_3 CH = CH_2} (CH_3 - CH _2 - CH _2)_3 B\)\(\xrightarrow {H_2 O_2 / \bar {O}H} \underset {Propan - 1 -ol \,(Major)}{CH_3 - CH_2 -CH_2 - OH}\)

Statement I is incorrect but Statement II is correct.
