Question 3(2020)

Write a balanced chemical equation for each of the following:

(i) Producing ethane from bromoethane using Zn/Cu couple in alcohol.

(ii) Complete combustion of ethane

Answer

(i) Ethane from bromoethane using Zn/Cu couple in alcohol

C2H5Brbromoethane+2[H]nascent hydrogenalcoholZn/Cu coupleC2H6ethane+HBr\underset{\text{bromoethane}}{\text{C}_2\text{H}_5\text{Br}} + \underset{\text{nascent hydrogen}}{2\text{[H]}} \xrightarrow[\text{alcohol}]{\text{Zn/Cu couple}} \underset{\text{ethane}}{\text{C}_2\text{H}_6} +\text{HBr}

(ii) Complete combustion of ethane

2C2H6+7O24CO2+6H2O+Δ2\text{C}_2\text{H}_6 + 7\text{O}_2 \longrightarrow 4\text{CO}_2 + 6\text{H}_2\text{O} + \Delta
