Question

Identify the major products of the following reaction. Select all that apply: Br₂ hv.

a) Br
b) Br₂
c) HBr
d) Br⁻

Answer 1

The major products of the Br₂ hv reaction are HBr (hydrogen bromide) and Br⁻ (bromide ion). Br and Br₂ are not major products.

Step-by-step explanation:

The major products of the reaction Br₂ hv are:

1. HBr (hydrogen bromide): One of the bromine molecules (Br₂) is broken by the light (hv), creating two bromine atoms (Br). Each bromine atom then reacts with a hydrogen atom (H) to form HBr.
2. Br⁻ (bromide ion): After reacting with hydrogen atoms, the bromine atom (Br) gains one electron and becomes a negatively charged ion, Br⁻.

The other options, Br and Br₂, are not major products of this reaction.
