उत्तर
(a) Ethene into1,2- Dibromoethene:
when bromine gas is passed into inert solvent like CCI4 Containing dissolved ethene at room temperature, one molecule of Br2 adds across the double bond togive ethylene dibromide.
\[\ce{CH2 = CH2 + Br -> CH2Br - CH2Br}\]
(b) Ethene to bromoethane:
Ethene reacts with halogen acids to form alkyl halidies.
\[\ce{CH2 = CH2 + HBr -> CH3 - Ch2Br}\]
