Per NCERT §9.3.1, in ethene the C-C bond consists of which σ/π combination, and the carbons are which hybridisation?
A1 σ + 1 π; sp²
B1 σ + 2 π; sp
C3 σ; sp³
D2 σ; sp³
Answer & Solution
Correct answer: A. 1 σ + 1 π; sp²
NCERT §9.3.1: C=C is 1 σ (sp²-sp²) + 1 π (parallel p overlap). Carbons are sp² hybridised, trigonal planar.
