Question

In the organic compound CH₂=CH–CH₂–CH₂–C≡CH, the pair of hydridised orbitals involved in the formation of: C₂ – C₃ bond is:

(a) sp – sp²(b) sp – sp³(c) sp² – sp³ (d) sp³– sp³

Answer 1

In the given organic compound, the carbon atoms numbered as 1, 2, 3, 4, 5, and 6 are sp, sp, sp³, sp³, sp², and sp² hybridized respectively. Thus, the pair of hybridized orbitals involved in the formation of C₂-C₃ bond is sp – sp³.
