1 of 1
Analyzing +4 | -1
Assertion (A): All the carbon atoms in H2C=C=CH2{H_2}C = C = C{H_2} are SP2S{P^2} hybridized

Reason (R): CH2=C=CH2C{H_2} = C = C{H_2} is a planar molecule
View answer and explanation
Correct option: D
Both A and R are false
Option D is correct because the central carbon in allene (H₂C=C=CH₂) is sp hybridized, not sp², and the molecule is non-planar due to the perpendicular arrangement of the CH₂ groups.
