4.
About the hybrid atomic orbitals it is correct to say that:
a.
are antibonding
b.
are bonding
c.
they only form sigmay pi links
d.
they have a defined spatial orientation
9.
Choose the correct premise
a.
the pi bonds are formed only from the frontal overlap of
orbitals
b.
The orbitals s can form sigma bonds
c.
The formation of sigma bonds is the result of the overlap of hybrid
orbitals exclusively
d.
a pi bond is formed...
draw the pi molecular orbitals that are produced from the
combination of the four p atomic orbitals in 1,3-butadiene. Label
each of the molecular orbitals as bonding, anti-bonding, or
non-bonding and add an appropriate number of electrons to the
molecular orbital diagram
