CFP1 summer paper general feedback Flashcards
1
Q
When are SN1 reactions used?
A
Tertiary and secondary alcohols. There must be steric hinderance
2
Q
When are SN2 reactions used?
A
Primary and secondary alcohols with little hinderance.
3
Q
How do you predict the outcome of a reaction?
A
Each reaction as specific reagents. By identifying them

Q
Determine the hybridisation state of N
A
copycat rule works because count the number of bonds (3) but one is lone pair and participates in resonance so is sp2 not 3 [for sp2 hybridised]
NH4+ is sp3 regardless
