In the compound
`CH_(2)=CH-CH_(2)-CH_(2)-C-=CH` the `C_(2)-C_(3)` bond is of

Options

A. `sp-sp^(2)`
B. `sp^(2)-sp^(3)`
C. `sp-sp^(3)`
D. `sp^(3)-sp^(3)`

Answer

b

Explanation

The correct numbering of parent chain is
`overset(1)(C)H_(2)=overset(2)(C)H-overset(3)(C)H_(2)-overset(4)(C)H_(2)-overset(5)(C)-=overset(6)(C)H`
Double and triple bond are equidistant from teminals, numbering is done in alphabetical order, giving lower number ot ene.
Hence, `C_(2)=C_(3)` are `sp^(2)-sp^(3)` hybridised
