Q12 / 90 · JEE Main 2024 (09 Apr Shift 2) · Chemistry

The incorrect statement regarding ethyne is

A
The $\mathrm{C}-\mathrm{C}$ bonds in ethyne is shorter than that in ethene
B
Both carbons are sp hybridised
C
Ethyne is linear
Correct answer
D
The corbon - carbon bonds in ethyne is weaker than that in ethene

Solution

The carbon-carbon bonds in ethyne is stronger than that in ethene. $(\mathrm{H}-\mathrm{C} \equiv \mathrm{C}-\mathrm{H})$ Ethyne is linear and carbon atoms are SP hybridised.

Hence, the correct answer is option: 'D'.
