what is the molecular orbital
the combined orbital formed when atomic orbitals overlap and share electron pairs
how are sigma bonds formed
through the head-on/axial overlap of 2 atomic orbitals
what type of orbitals can overlap to form sigma bonds
s and s
s and p
p and p
where is the electron density in a sigma bond
between the two nuceli along the bond axis
is the electron density in a pi bond symmetrical
yes
what type of bond is always a sigma bond
a single covalent bond
how are pi bonds formed
through the sideways/lateral overlap of adjacent p orbitals
where is the electron density in a pi bond
above and below the internuclear plane of the bonding orbtials
