- What type of reaction has A undergone?
- What is your observation?
- Name (not formula) the compound formed when steam reacts with A in the presence of phosphoric acid.

उत्तर
- CH2 = CH2
- Addition reaction
- Reddish brown colour of bromine gets discharged.
- \[\ce{\underset{Ethene}{CH2 = CH2} + H2O ->[Phosphoric][acid] \underset{Ethanol}{CH3 - CH2 - OH}}\]
- By dehydration (with any dehydrating agent).
\[\ce{\underset{Ethanol}{C2H5OH} ->[Al2O3][300^\circ C] \underset{Ethene}{C2H4} + H2O}\]
