Problem :
Allene has the following molecular structure:
Problem 2
Give a complete valence bond picture of allene, including all
σ
and
Π
interactions. (Hint: allene is not a planar molecule.)
Solution
The center carbon is
sp
hybridized while the end carbons are
sp
2
. The
hydrogens
on one end of the molecule are perpendicular to those on the other end.
