m3: alcohols/phenols/ethers

what is produced from a dehydration of an alcohol at a higher temperature?

an alkene and H₂O

what is produced from the dehydration of an alcohol at a lower temperature?

an ether

what is produced from the oxidation of a primary alcohol?

an aldehyde and water

what is produced from the oxidation of an aldehyde?

carboxylic acid

what is produced from the oxidation of a secondary alcohol?

a ketone and H₂O

can a ketone be oxidized?

no

can tertiary alcohols be oxidized?

no, because there is no hydrogen on the carbon to which the hydroxyl group is attached

why are phenols able to act as weak acids?

the negative charge of the oxygen (after donating a proton) is stabilized by resonance that can occur with the aromatic group

do phenols form stronger or weaker hydrogen bonds?

stronger, because the dipole is stabilized by resonance with the aromatic group

do phenols have higher or lower melting and boiling points?

higher, due to the fact that they can form stronger hydrogen bonds

what is the structure of an ether?

R-O-R

can ethers form hydrogen bonds?

they can with H₂O, but not in pure state

do ethers have a higher or lower boiling point than alcohols?

lower, because they cannot form hydrogen bonds in the pure state, and are less polar

do ethers react easily?

no, but they are very flammable (can undergo combustion reactions)
