Even though acetals contain C-O-R bond, acetals are not ethers. Acetals have 2 OR groups attached to a single C atom. But an ether has one O atom which is bonded to 2 carbons.
Alcohols are compounds which have OH groups.
(b)
Interpretation:
The functional groups in the following compound should be labeled as an alcohol, ether, acetal or hemiacetal:
Concept Introduction:
The addition of one molecule of alcohol to an aldehyde or ketone results in a hemiacetal. Here, the C=O double bond breaks and single bonds are formed. If the hemiacetal is acyclic, it is not stable. Acyclic hemiacetal reacts with a second alcohol molecule and forms acetal.
Even though acetals contain C-O-R bond, acetals are not ethers. Acetals have 2 OR groups attached to a single C atom. But an ether has one O atom which is bonded to 2 carbons.
Alcohols are compounds which have OH groups.
