The correct options are
A C6H5CH2CH(OH)CH3+PBr3→
C C6H5CH=CHCH3+HBr+benzoylperoxide→
2-Bromo-3-phenylpropane can be synthesized by reactions A and
B. In reaction A, -OH group is replaced with Br.
(A) C6H5CH2CH(OH)CH3+PBr3→C6H5CH2CH(Br)CH3
In the reaction B, a molecule of HBr is added across C=C bond.
(B) C6H5CH=CHCH3+HBr+benzoylperoxide→C6H5CH2CH(Br)CH3
In the reaction C, 1-Bromo-1-phenylpropane is obtained.
(C) C6H5CH2CH2CH3+Br2+light→C6H5CHBrCH2CH3
