Question

Hybridization of Carbon atoms in 1,5 hexadiene​

Answer 1

Explanation:

First, the double bonds may be separated by one or more sp3-hybridized carbon atoms, as in 1,5-hexadiene. In this circumstance each double bond behaves independently of the other, and we refer to them as isolated. ... The central carbon atom in such a system is sp-hybridized, and we call such double bonds cumulated.
