Which of the compounds above would react to take up two molecules of bromine during bromination?

Answer Details

The compound that would react to take up two molecules of bromine during bromination is l only. This is because l has a double bond between carbon and carbon, which allows it to undergo addition reactions, such as bromination. The double bond is broken, and a bromine atom is added to each carbon atom, resulting in the product with two bromine atoms attached to it. On the other hand, lll has no double bonds and cannot undergo addition reactions like bromination. Therefore, l and ll only have double bonds and can react to take up two molecules of bromine during bromination.
