The Cylindrical Shape Of An Alkyne Is Due To Chemistry Question

The cylindrical shape of an alkyne is due to


(a) two sigma C – C and one π C – C bonds
(b) one sigma C – C and two π C – C bonds
(c) three sigma C – C bonds
(d) three π C – C bonds

Correct Answer:

one sigma C – C and two π C – C bonds


In alkyne, two carbon atoms constituting the triple bond are sp-hybridised. Carbon undergoes sp-hybridisation to form two sp-hybride orbitals. The two 2p-orbitals remain unhybridised. Hybrid orbitals forms one sigma bond while two π- bonds are formed by unhybridised orbitals.
