Question

For the 3d molecular structure of allene, how come there is no wedge and dash on the right side? The explanation given by the textbook does not make sense to me. If there are two double bonds, why does one side have to be perpendicular to the other?

 

 

1-20 Carbon-2 is sp hybridized. If the p orbitals making the pi bond between C-1 and C-2 are in the plane
of the paper (putting the hydrogens in front of and behind the paper), then the other p orbital on C-2 must
be perpendicular to the plane of the paper, making the pi bond between C-2 and C-3 perpendicular to the
paper. This necessarily places the hydrogens on C-3 in the plane of the paper. (Models will surely help.)
