Question

21 multiple choice 2 points what is the product when ethene reacts with bromine in ccl₄? 1,2 - dibromoethane ethanol ethane ethylene glycol

Explanation:

Step1: Understand the reaction type

Ethene undergoes an addition reaction with bromine.

Step2: Write the reaction equation

$$CH_2=CH_2 + Br_2 \xrightarrow{CCl_4} CH_2Br - CH_2Br$$
The product formed is 1,2 - dibromoethane. Ethanol is formed when ethene reacts with water in the presence of an acid catalyst. Ethane is formed when ethene undergoes hydrogenation. Ethylene glycol is formed when 1,2 - dibromoethane reacts with aqueous sodium hydroxide (followed by acidification).

Answer:

1,2-dibromoethane
