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
C6H2=5CH−C4H2−C3H2−2C≡1CH
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
