MCQ
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
  • ✓
    The carbon-carbon bonds in ethyne is weaker than that in ethene
✓

Answer

Correct option: D.
The carbon-carbon bonds in ethyne is weaker than that in ethene
d
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.
