Draw structures for molecules that fit the following descriptions:
(a) C₃H₆O containing an aldehyde functional group

An aldehyde is a type of organic compound characterized by the presence of a carbonyl group (C=O) bonded to a terminal carbon atom. This means that the carbonyl group is located at the end of the carbon chain, which distinguishes aldehydes from ketones, where the carbonyl group is found within the chain. Aldehydes typically have the general formula RCHO, where R represents a hydrocarbon group.

The molecular formula C3H6O indicates that the molecule contains three carbon atoms, six hydrogen atoms, and one oxygen atom. Understanding how to interpret this formula is crucial for constructing the molecular structure, as it provides insight into the number of bonds and the arrangement of atoms. The presence of fewer hydrogen atoms relative to carbon suggests the potential for functional groups, such as the aldehyde in this case.

Drawing structures for organic molecules involves representing the arrangement of atoms and the types of bonds between them. This can be done using various methods, such as Lewis structures or skeletal formulas. For the given molecular formula C3H6O with an aldehyde group, one must ensure that the carbonyl group is positioned at the end of the carbon chain while satisfying the tetravalency of carbon and the valency of other atoms involved.
