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.

i believe i understand sigma and pi for covalent bonds...
however do not understand sigma and pi bonds for ionic bonds.
so what are properties of ionic sigma pi bonds...can
you/we sketch them. what makes them different from convalent sigma
pi bonds? TY

b) Fe > Ni > Co > Cu
c) Cu > Ni > Co > Fe
d) Cu > Fe > Ni > Co
Suppose Sigma Industries and Pi Technology have identical assets
that generate identical cash flows. Sigma Industries is an
all-equity firm, with 9 million shares outstanding that trade for a
price of $18.00 per share. Pi Technology has 24 million shares
outstanding, as well as debt of $48.60 million. a. According to MM
Proposition I, what is the stock price for Pi Technology? b.
Suppose Pi Technology stock currently trades for $12.68 per share.
What arbitrage opportunity is available? What assumptions...
