`n-`Butane `(C_4H_(10))` is produced by monobromination of `C_2H_6` followed by Wurtz reaction. Calculate the volume of ethane. The bromination takes place with `90%` yeild and the wurtz reaction with `85%` yield.A. 27.75 litresB. 55.5 litresC. 111 litresD. 5.55 litres |

Answer» Correct Answer - B `2C_2H_6+Br_2rarr2C_2H_5Br+HBroverset(2Na)toC_4H_(10)` `12xx4+10=58gm` 58 gm of n-butene `implies2xx22.4` litre of `C_2H_6` at STP i.e., `2xx22.4xx(100)/(85)xx(100)/(90)` `=58.56` litre at STP `58gm` of n-butate`=58.56` litre `55gm` of n-butane`=55.5` litre |
