Question

The state of hybridisation of `C_(2),C_(3),C_(5) and C_(6)` of the hydrocarbon -
`{:(" "CH_(3)" " CH_(3)),(" "|" "|),(CH_(3)-C-CH=CH-CH-C-=CH),(""^(7)" "^(6)| " "^(5)" "^(4)" "^(2) " "^(1)),(" "CH_(3)):}`
is in the following sequence :
A. `sp, sp^(2),sp^(3) and sp^(2)`
B. `sp, sp^(3),sp^(2) and sp^(3)`
C. `sp^(3),sp^(2),sp^(2) and sp `
D. `sp, sp^(2),sp^(2) and sp^(3)`

Answer 1

Correct Answer - B
`C_(2)` having `to 2-sigma` bond `to `sp
`C_(3)` having `to 4-sigma` bond `to sp^(3)`
`C_(5)` having ` to 3-sigma` bond ` to sp^(2)`
`C_(6)` having ` to 4- sigma ` bond ` to sp^(3)`
