Question: Analyse the following reaction and identify the nature of $ A $ and $ B $ [Kerala CET 2005] $ B\underset{hv}{\mathop{\xleftarrow{HBr}}} $ $ \xrightarrow{HBr}A $
Options:
A) Both A and B are correct
B) Both A and B are correct
C) A is and B is
D) A is and B is
E) A is & B is
Show Answer
Answer:
Correct Answer: C
Solution:
$ \xrightarrow{HBr}A $ Formation of A is a electrophilic addition reaction (i) $ HBr\to {H^{+}}+B{r^{-}} $ (ii) $ +{H^{+}}\to \overset{+}{\mathop{C_6H_5CHCH_3}} $
$ \underset{hv}{\mathop{\xrightarrow{}}}\text{B} $ Formation of B is a free radical addition reaction (i) $ HBr\xrightarrow{hv}\overset{\bullet }{\mathop{H}}+\overset{\bullet }{\mathop{Br}} $ (ii) (iii)
