Question 1

Is aldehyde or ketones more reactive and why?

Answer 1

Aldehydes, due to less steric hindrance and electronics (R groups provide stabilisation)

Question 2

For reactions between Strong and Weak nucleophiles, what is the first step?

Answer 2

Strong: Nu attacks first and pie bond breaks forming O-

Weak: Pi bond break first forming bond with Electrophile

Question 3

how do you form an imine?

Answer 3

Addition of Amine onto a ketone or aldehyde

Question 4

Reaction chain to get from alcohol to imine

Answer 4

Primary alcohol (oxidise)
Aldehyde (Addition)
Imine

Question 5

What functional group is used to convert Aldehydes and ketone into Hemiacetals or acetals

Answer 5

Aldehyde + alcohol = hemiacetal

Hemiacetal + alcohol = acetal
