Question 7

what is resonance theory?

Answer 7

‘hypothetical structures that can’t be isolated’
a molecule, ion or radical of the the resonance structures will best represent the weighted hybrid.

Answer 9

2 electrons moving

Question 10

what does a half arrow head represent?

Answer 10

1 electron moving

Question 11

rules for movement of electrons?

Answer 11

curly arrows much start from an electron (rich species)
arrow head must go towards electron
