Answer

Molecular formula: $CH _3- CH _2- OH$ and name: Ethanol.. When it is heated with an excess of conc. Sulphuric acid elimination of water molecule takes place to give ethane.$\text{C}_2\text{H}_5\text{OH}+\text{H}_2\text{SO}_4\xrightarrow{\Delta}\text{CH}_2=\text{CH}_2+\text{H}_2\text{O}+\text{H}_2\text{SO}_4$
