When ethyne is passed through a red hot tube, then the formation of benzene takes place:
Calculate the standard heat of trimerisation of ethyne to benzene.
Explanation for correct option:
(C)
Step 1: Trimerization reaction:
Step 2: Standard heat of formation calculation:
Step 3: Substitution of values:
So, this is the correct option.
Explanation for incorrect option:
Since the correct option is . Therefore, options (A), (B) & (D) are incorrect.
Therefore, the correct option is (C) .
