Question

Hybridization of the carbon atom indicated by (*) in

CH3-*CH2-CH3,*CH=CH2 , and CH3-*C-C≡H is __________, __________, and __________, respectively.

A)
B)
C)
D)
E)

Answer 1

The carbon atoms indicated by (*) have hybridizations of sp3, sp2, and sp, respectively, corresponding to the types of bonds they are involved in: single, double, and triple bonds.

Step-by-step explanation:

The hybridization of the carbon atom indicated by (*) in CH3-*CH2-CH3, *CH=CH2, and CH3-*C-C≡H is sp3, sp2, and sp, respectively. The carbon atoms indicated by (*) have hybridizations of sp3, sp2, and sp, respectively, corresponding to the types of bonds they are involved in: single, double, and triple bonds.

In the first molecule, CH3-*CH2-CH3, all carbons are surrounded by four single bonds, indicating sp3 hybridization. For the second molecule, *CH=CH2, the carbon with the asterisk is part of a double bond, which is characteristic of sp2 hybridization. Finally, in CH3-*C-C≡H, the indicated carbon is part of a triple bond, suggesting sp hybridization.
