30. Addition of HBr to 2-methyl-1-propene in the
presence of hydrogen peroxide produces
(1) 1-Bromobutane
(2) 2-Bromopropane
(3) 2-Bromo-2-methylpropane
(4) 1-Bromo-2-methylpropane
The explanation for the correct option:Option(1) 1-Bromobutane
Addition of HBr to 2-methyl-1-propene
The addition of Addition of HBr to 2-methyl-1-propene in the presence to hydrogen peroxide produces 1-Bromobutane
The reaction is given as:
CH3−(CH3)C=CH2HBr,H2O2−−−−−−−−→CH3−(CH3)CH−CH2Br
The reaction follows anti-markonikoff's addition.
The Anti-Markovnikov rule defines regiochemistry in which the substituent is attached to a less substituted carbon instead of the more substituted carbon.
This is because substituted carbocation allows for more hyperconjugation and indution, resulting in a more stable carbocation.
The reaction proceed as:
H2O2hv−→2O.H
HBr+O.H⟶H2O+Br.
CH3−(CH3)C=CH2Br.−−→CH3−(CH3)C.−CH2BrH..−−→CH3−(CH3)CH−CH2Br
Hence, Option(1) 1-Bromobutane is the product obtained on the Addition of HBr to 2-methyl-1-propene in the presence to hydrogen peroxide.
