20
Q

What is used if aldehyde is attached to a ring?

A

Suffix –carbaldehyde

21
Q

In the presence of water, aldehydes and ketones react to form

A

Geminal diols

22
Q

In the presence of alcohol, aldehydes and ketones react to form

A
  • Hemiacetals

- Hemiketals

23
Q

Imines and related compounds can undergo tautomerization to form

24
Q

Aldehydes and ketones can also undergo reduction to form alcohols via

A
  • LiAlH4

- NaBH4

25
The carbonyl carbon is
Electrophilic
26
The carbonyl carbon is
Electron-withdrawing
27
KMnO4 allows for aldehydes to become
COOH
28
LiAlH reduces aldehydes to
Primary alcohols
29
LiAlH reduces ketones to
Secondary alcohols
30
Why is it difficult to isolate hemiacetals and hemiketals?
- Unstable molecules | - hydroxyl group is rapidly protonated, leaving behind carbocation
