Which statement best describes the pi bonding in ethyne?
A) There are two pi bonds created through the overlap of unhybridized 2p atomic orbitals on each C atom.
B) There are two pi bonds created through overlap of sp hybrid orbitals on each C atom.
C) There is one pi bond created through overlap of a 2p hybridized atomic orbital on each C atom.
D) There is one pi bond created through overlap of sp unhybridized atomic orbitals on each C atom.
E) There are two pi bonds created through overlap of an sp hybrid orbital on each C atom and a 1s unhybridized atomic orbital on each H atom
Why is the answer A, and not B? How can we determine whether or not C in ethyne is hybridized or unhybridized?
