Question

Formation of polyethene from calcium carbide takes place as follows:
$C a C_{2} + H_{2} O \to C a (O H)_{2} + C_{2} H_{2} C_{2} H_{2} + H_{2} \to C_{2} H_{4}$
$n (C_{2} H_{4}) \to (- C H_{2} - C H_{2} -)_{n}$
The amount of polyethylene possibly obtainable from 64.0 kg $C a C_{2}$ can be:

Solution

The correct option is A 28 kg
64 g $C a C_{2}$ contains 24 g carbon.
All the carbon from calcium carbide is present in polyethylene.
Polyethene is $(C H_{2})_{n}$ , i.e., 14 gram of polythene contains 12 gram of carbon. Hence, 24 gram carbon will be contained in $\frac{14}{12} \times 24 = 28$ g of polyethene.
Therefore, 64 g $C a C_{2}$ will produce 28 g polythene.
Hence, 64 kg $C a C_{2}$ will produce 28 kg polythene.
