Question

Triple bond of ethyne is made of or Cylindrical shape of an
alkyne is due to
(a) Three σ – bonds
(b) Three π – bonds
(c) Two σ and one π – bond
(d) Two π and one σ – bond

Answer 1

Option (d) is the right answer.

Triple bond of ethyne is made up of two (π-bond) and one (σ–bond)

- Ethyne is a linear molecule in organic chemistry and consists of sp hybridization.

- In the structure of ethyne , the triple bond between the two carbon atom consists of a sigma bond.

- It's situated between the two sp² orbitals and also between the two (pi-bonds) between the set of two p-orbitals.
