Question

(iii) The central carbon in propadiene is shows which hybridization
​

Answer 1

the hybridization is sp

Answer 2

Explanation:

The simplest cumulated diene is 1,2-propadiene, CH2=C=CH2, also known as allene. Indeed, cumulated dienes are often called allenes. The central carbon in such compounds is sp-hybridized (it has only two bonding partners), and the double bond array is linear as a result.
