Question

Reaction of preparation of ethane from ethyl bromide

Answer 1

Explanation:

C2H5Br + 2 (H)___> C2H6 + HBr

catalyst: Zn/Cu couple, alcohol

Answer 2

Ethyl bromide ( C$_{2}$H$_{5}$Br ) can be converted into ethane ( C$_{2}$H$_{6}$ ) by following steps of reaction -

(i) React ethyl bromide with aqueous KOH to form ethanol ( C$_{2}$H$_{5}$OH ) .

(ii) React ethanol with red phosphorous in the presence of hydrogen iodide ( HI ) to form ethane .

• The molar mass of ethane ( C$_{2}$H$_{6}$ ) is 30.07 g/mol .
• Red P in HI is used to generate Nascent Hydrogen .
