Q

why can’t tertiary alcohol be oxidized

A

because the carbon atom attached to the hydroxyl group doesn’t have any other hydrogen atoms attached

Q

what is the problem with aldehydes

A

they are easily oxidized so they may be oxidized further by gaining oxygen (between the CH) to form a carboxylic acid with the equation of RCOOH

16
Q

when primary alcohol is fully oxidized with potassium dichromate(IV) and sulfuric acid what is formed

A

carboxylic acid (ends with noic) propanoic

17
Q

when secondary alcohol is oxidized with potassium dichromate(IV) and sulfuric acid what is formed

A

water and ketones (end with none) example is propanone

18
Q

what is heated under reflex purposed for

A

to undergo full oxidization to form a ketone or a carboxylic acid

19
Q

what is heating under reflex

A

a reaction mixture with a condenser fitted vertically

20
Q

how is it possible for oxidization to be fully undergone in heating under reflux

A

it is possible because it doesn’t allow the products of oxidization to leave the mixture if they boil they will be condensed back down

21
Q

what is the purpose of distillation with addition

A

to undergo incomplete oxidization to form aldehydes

22
Q

what is distillation with addition

A

the heating of a reaction mixture (oxidizing reagent), but adding another liquid (alcohol) and distilling the products formed (aldehydes)

23
Q

how does distillation able to help with undergoing incomplete oxidization

A

it distills off the aldehydes to a receiver with a lower temperature (doesn’t go back to the oxidization mixture)
