Aldehydes and Ketones I

Question 1

carbonyl

Answer 1

double bond between a carbon and oxygen

Question 2

pyridinium chlorochromate (PCC)

Answer 2

only reagent that can oxidate a primary alcohol to an aldehyde

Question 3

geminal diols

Answer 3

aldehyde/ketones react with water to form these

Question 4

hemiacetal/hemiketal

Answer 4

when an aldehyde or a ketone is attacked by an alcohol, it will attach and make the carbonyl into an alcohol

Question 5

acetal/ketal

Answer 5

when attacked with more alcohol, the carbonyl is completely replaced

Question 6

imine

Answer 6

nitrogen atom double bonded to a carbon

Question 7

enamine

Answer 7

compound with a double bond and a nitrogen

Question 8

cyanohydrin

Answer 8

-OH and -CN group

Question 9

formation of carboxylic acid from aldehyde

Answer 9

performed by any oxidizing agent stronger than PCC: KMnO4, CrO3, Ag2O, H2O2

Question 10

hydride reagents

Answer 10

turn aldehydes and ketones into alcohols; LiAlH4 NaBH$
