NEETChemistryRedox Reactions
Match the following column-I and column-II : ( array |l|l|l|l| & Column I & & Column II (a) & H ₂ S & (p) & Oxidising agent (b) & KMnO ₄ & (q) & Reducing agent (c) & H ₂ O ₂ & (r) & array l Can acts as both oxidising and reducing agent array array )
Options
- A(a-r),(b-p),(c-q)
- B(a-q),(b-p),(c-r)
- C(a-p),(b-q),(c-r)
- D(a-r),(b-q),(c-p)
Correct answer
B. (a-q),(b-p),(c-r)
Step-by-step solution
Let's match the substances: - (a) ( H _ 2 S ) : It is a reducing agent (since sulfur in ( H ₂ ~S ) can be oxidized). So, match (a) with (q). - (b) ( KMnO ₄ ) : It is a strong oxidizing agent (especially in acidic medium). So, match (b) with (p). - (c) ( H _ 2 O _ 2 ) : It can act as both an oxidizing and reducing agent depending on the reaction. So, match (c) with (r). Thus, the correct matching is: ((a-q),(b-p),(c-r) ).
