Question

What is the hybridization of the central carbon of allene (1,2-propadiene)?
Options
A sp
Correct Answer
B sp2
C sp3
D p
Correct Answer

Option A is the correct answer.

Detailed Explanation

The central carbon in allene (CH2=C=CH2) forms two double bonds (two sigma and two pi bonds). It has two sigma bonds, so it is sp hybridized with a linear geometry.

Hint

What hybridization is associated with two sigma bonds?
