Q.
The state of hybridization of C2, C3, C5 and C6 of the hydrocarbon CH₃–C(CH₃)₂–CH=CH–CH(CH₃)–C≡CH (numbered from the right: C≡CH carbons are C1 and C2, the CH(CH₃) carbon is C3, CH=CH are C4 and C5, the C(CH₃)₂ carbon is C6, end CH₃ is C7) is in the following sequence:
A) sp³, sp², sp² and sp
B) sp, sp², sp² and sp³
C) sp, sp², sp³ and sp²
D) sp, sp³, sp² and sp³
Explanation
[Solution from source] C2 is a triple-bonded carbon (sp). C3 is the CH(CH₃) carbon with only single bonds (sp³). C5 is a double-bonded carbon (sp²). C6 is the quaternary C(CH₃)₂ carbon (sp³). So the sequence is sp, sp³, sp², sp³. Answer (4).
