Question:
Can a sigma bond and pi bond occur at the same time for the
same reaction??
Replies:
Dear Jessica,
I'm not sure what you mean by "occur," but it is not usually possible
to have a pi bond without also having a sigma bond (although
it is common to have a sigma bond without a pi bond). This is
because pi bonds form from the sideways overlap of unhybridized
p orbitals, whereas sigma bonds in a pi-bonding situation form
from the head-to-head overlap of hybrid orbitals (sp or sp^2).
I hope this helps - try rewording your question if this
answer wasn't sufficient.
