L2 Flashcards
1
Q
Is aldehyde or ketones more reactive and why?
A
Aldehydes, due to less steric hindrance and electronics (R groups provide stabilisation)
2
Q
For reactions between Strong and Weak nucleophiles, what is the first step?
A
Strong: Nu attacks first and pie bond breaks forming O-
Weak: Pi bond break first forming bond with Electrophile
3
Q
how do you form an imine?
A
Addition of Amine onto a ketone or aldehyde
4
Q
Reaction chain to get from alcohol to imine
A
Primary alcohol (oxidise)
Aldehyde (Addition)
Imine
5
Q
What functional group is used to convert Aldehydes and ketone into Hemiacetals or acetals
A
Aldehyde + alcohol = hemiacetal
Hemiacetal + alcohol = acetal
