Let us look at the structures of a few naturally occurring aldehydes, which are given below.Įxcept for formaldehyde, a gas at room temperature, the most common aldehydes, and ketones are liquid at ordinary temperatures. For example, an oral contraceptive and methandrostenolone, the synthetic steroids norethindrone, and an anabolic steroid contain a carbonyl group.
The other example of a common name is alpha ionone, which is a fragrant ketone responsible for the scent of irises, used in perfumes.Ĭarbonyl groups are there in some steroids. The first part of the name shows that this compound is present in the retina, whereas the suffix tells us it is an aldehyde. For example, retinal is an aldehyde that is required for vision. Else, we use the suffix '-one' if the carbonyl compound is a ketone. We use the suffix '-al' if the carbonyl compound is an aldehyde. In common names, one of the two suffixes may indicate the presence of a carbonyl group in a molecule. The most common functional group in the oxygen-containing organic compounds isolated from the biological sources is the carbonyl group. The safeguards concerning irritant properties must also be most extensive for the lower members and those with either an unsaturated or substituted chain. Explosion and fire precautions must be most rigorous in the lower members of the aldehyde family case.
Many aldehydes are flammable liquids and volatile, where at normal room temperature from vapor in the explosive concentrations. R can be a hydrocarbon or hydrogen radical, which is substituted or unsubstituted.
Aldehyde definition or the aldehyde meaning can be given as the members of an organic chemical compounds class, represented by the general structural formula as R-CHO.
