chp 16 Flashcards
1
Q
activating groups = ortho para
A
NH2, Oh, NHC=O
Carbon chains
2
Q
deactivating group = meta
A
NO2, NH3, Cf3, CN, C=O,So3h
3
Q
deactivating group that ortho para
A
halogens
4
Q
resonance reasoning for ortho para
A
ortho para groups donate electrons therefor it is stable when the carbocation is connected to the directing group
5
Q
resonance reasoning for meta
A
having a carbocation attached to the directing group is unstable bc the group is trying to pull electrons
6
Q
clemenson reduces ____ with _____
A
reduces both NO2, and c=O
Zn, Hg, Hcl, H2 and heat
7
Q
reduction of only NO2
A
NO2 to NH2
Sn, Hcl
8
Q
Reducing from NO2 to NH2 leads to
A
Meta tot ortho para
9
Q
FC limitations
A
no FC with meta directing groups
no acylation with strong activating
10
Q
Sulfanation
A
SO3, H2SO4
11
Q
Nitration
A
HNO3, H2SO4
