Question

The number of sigma and \(\pi\)-bonds in ethyne molecule:

• A. 1 sigma, 1 \(\pi\)
• B. 2 sigma, 2 \(\pi\)
• C. 2 sigma, 1 \(\pi\)
• D. 3 sigma, 2 \(\pi\)

Hint:

Ethyne (C2H2) has two sigma bonds and two pi bonds due to the triple bond between the carbon atoms.

Answer 1

The Correct Option is B

In ethyne (C2H2), there are two sigma bonds (one from each C-H and C-C bond) and two pi bonds (one from the overlap of p orbitals of the two carbon atoms).
