P-Block Elements Ques 618
Question: Which of the following is the best description for the behaviour of bromine in the reaction given below? $ H_2O+Br_2\to HOBr+HBr $
Options:
A) Proton acceptor only
B) Both oxidized and reduced
C) Oxidized only
D) Reduced only
Show Answer
Answer:
Correct Answer: B
Solution:
$ H_2O+\overset{0}{\mathop{B}}r_2\xrightarrow{{}}HO\overset{+1}{\mathop{Br}}+H\overset{-l}{\mathop{Br}} $ Thus here oxidation number of Br increases from 0 to +1 and also decreases from 0 to -1. Thus it is oxidised as well as reduced.
