JEE Advance - Chemistry (2012 - Paper 1 Offline - No. 6)
In allene (C3H4), the type(s) of hybridisation of the carbon atoms is (are):
sp and sp3
sp and sp2
only sp3
sp2 and sp3
توضیح
The structure of allene is CH2 = C = CH2 . Here both the terminal carbons are sp2 hybridised while the central carbon is sp hybridised.
