Question

1 mole of 50% pure CaC2 on hydrolysis followed by passing through red hot copper tube. How many moles of
Benzene is formed
a) 1/2
b) 1/5
c) 16
d) 18​

Answer 1

Answer:

1 / 5

Explanation:

option b is correct

Answer 2

The correct answer is option C i.e, $\frac{1}{6}$

Given,

1 mole of 50% pure CaC2 on hydrolysis followed by passing through a red hot copper tube.

To Find,

Moles of Benzene formed

Solution,

Reaction:

$CaC_{2} +2H_{2} O =$ CH≡CH +$Ca(OH)_{2}$

Also, since it is passed through a red hot copper tube,

reaction,

3CH≡CH→$C_{6} H_{6}$

This means,

3 moles  $C_{2} H_{2}$ gives 1 mole of benzene

hence, 0.5 moles of $C_{2} H_{2}$ gives $\frac{1}{6}$ moles of benzene.
