Per NCERT §4.6.2 (ethyne C₂H₂), the C-C triple bond is composed of which bonds, and the carbon atoms are which hybridisation?
AThree σ bonds; sp³
BOne σ + two π bonds; carbons are sp hybridised
COne σ + one π; sp²
DThree π; sp
Answer & Solution
Correct answer: B. One σ + two π bonds; carbons are sp hybridised
Per NCERT §4.6.2 sp ethyne: C≡C = 1 σ (sp-sp) + 2 π (from two unhybridised p orbitals). Linear H-C≡C-H.
