-For the diatomic molecules, how does one determine bonding and non-bonding pairs with respect to the central atom as there is no central atom?

With some help with reb, i have chagned the question to...

Check that these are correct, cause I'm not sure

H2-None
O2-None
N2-None
HCl-None
CO2-sp
H2S-none
H30+1-sp2
ClNO-none
NH2-1 -None
SnCl5-1 - sp3d
ClF4+ - sp3d
ICl3 - sp3d
ClF2-1 - sp3d
PCl6-1 - sp3d2
PI5 - sp3d
SF6 - sp3d2
IF5 -sp3d
C2H6 - sp3 on both of the carbons
C2H2 - sp on both of the carbons
NCl3 - none
XeF4 - sp3
NO2 - not sure

Answer 1

Firstly, it is outrageous to put 24 problems on here and expect someone to do your homework like this.

Single bonds are SP3
Double bonds are SP2
Triple bonds are SP

When there is no central atom, look at the element with the lower electronegativity.

Now you can do your work

Answer 2

Central atom in ____ is ____ COH2 sp² H2O sp³ PCl5 sp³d Count the σ bonds and lone pairs about the atom
