(a)
Interpretation:
A compound that contains an acetal with the molecular formula C5H12O2 should be drawn.
Concept Introduction:
Addition of one molecule of alcohol to an
(b)
Interpretation:
A compound that contains a hemiacetal with the molecular formula C5H12O2 should be drawn.
Concept Introduction:
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.
(c)
Interpretation:
A compound that contains two ethers with the molecular formula C5H12O2 should be drawn.
Concept Introduction:
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.
(d)
Interpretation:
A compound that contains an alcohol and ether, but is not a hemiacetal with the molecular formula C5H12O2 should be drawn.
