electron withdrawing groups decreases basicity…

A

amines

1
Q

Amines

A

electron donating groups increase basisty/nucleophilicity

2

acetal vs hemi acetals

A

Acety.. has OR and OR group… Hemi has OR and OH group

14
Q

anomeric carbon

A

a sterocenter can point up or down…alpha down… beta up

15
Q

epimers

A

differ in only one sterogenic center… everything else is the same… very similar
