Question 1

why are the g and u labels not used for LiH

Answer 1

because neither has an inversion because it would change the position of the nuclei

Question 2

is antibonding or bonding distorted towards the electronegative hydrogen

Answer 2

the out of phase combination

Question 3

is the out of or in phase combination distorted towards the electropositive lithium

Answer 3

the in phase combination

Question 4

why is the lithiums contribution to the bonding orbital larger

Answer 4

because it is closer in energy to the 2s shell and also it is larger

Question 5

why does the pz interact with the 1s orbital with flourine and hydrogen

Answer 5

because the pz points towards the s orbital

Question 6

what does the in phase combination of 1s and pz orbitals look like

Answer 6

and hourglass with one backwards chunky side

Question 7

what does the out of phase combination of 1s and 2pz orbitals look like

Answer 7

like three ovals but the one over the hydrogen nucleus is biggest

Question 8

do you count non bonding central orbitals in the bond order

Answer 8

no

Question 9

where to put non bonding orbitals in the centre

Answer 9

at the same level as the atomic orbital

Question 10

are more electronegative energy levels higher or lower than less electronegative ones

Answer 10

lower
