Question

$C{H}_3\cdot CH=C=C{H}_2$ has:

• A. only $sp\text{-}$ hybridised carbon atoms
• B. both $sp$ and $sp\text{-}$ hybridised atoms
• C. only $s{p}^2\text{-}$ hybridised carbon atoms
• D. $sp,s{p}^2$ and $s{p}^3\text{-}$ hybridised carbon atoms

Answer 1

Answer: (D)

Carbon atom, whose valencies are satisfied with 4 single bonds, is $s{p}^3\text{-}$ hybrid. Carbon atom, whose valencies are satisfied with one double-bond, is $s{p}^2\text{-}$ hybrid while the carbon atom, whose valencies are satisfied either by 2 double-bonds or one triple and one single bond, is $sp\text{-}$ hybrid.
