Question

Which of the following statements about the first halogens is(are) accurate?

• A. The strongest reducing agent (from given) is iodine
• B. The most electronegative element is fluorine
• C. At room temperature, the liquid halogen is bromine
• D. The most reactive halogen is fluorine

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A

The strongest reducing agent (from given) is iodine

B

The most electronegative element is fluorine

C

At room temperature, the liquid halogen is bromine

D

The most reactive halogen is fluorine

Fluorine is a super halogen because it is by far the most reactive of the four. It also happens to be the strongest oxidizing agent of all elements. The first two - fluorine and chlorine are gases while bromine is a fuming brown liquid at room temperature. Iodine is a solid at room temperature. As we go down the group, the ability as an oxidizing agent decreases which arguably puts iodine as the strongest reducing agent from fluorine, chlorine, bromine and iodine!
