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– sp

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 .
