C. Br2
D. Br-​

Answer 1

mark me as brainliest

Explanation:

D.Br

Bromine is the strongest reducing agent among the following.

Answer 2

The strongest reducing agent is option (D) Br-.

• Reducing agents are those elements that can reduce others and oxidise themselves.
• Cl2 and Br2 are in the highest oxidation state and there is no chance of losing electrons so they can behave as oxidising agents by forming Cl- and Br- ions by gaining electrons.
• Cl- and Br- can change to their highest oxidation state and can form Cl2 and Br2 respectively. so, they are good reducing agents.
• Cl- is more electronegative than Br- so it will be difficult for Chloride ions to lose electrons than Br-. so, Br- is the strongest reducing agent.
