Answer:

The correct answer is D) R-CHO.

Step-by-step explanation:

The general formula of an aldehyde is R-CHO. In this formula, R represents a generic alkyl or aryl group, which can vary in size and structure. The -CHO group is called the aldehyde functional group, consisting of a carbon atom double-bonded to an oxygen atom and single-bonded to a hydrogen atom. Aldehydes are organic compounds that are characterized by the presence of the aldehyde functional group. They are typically named by replacing the -e ending of the corresponding parent alkane with -al. For example, formaldehyde (HCHO) is the simplest aldehyde, derived from methane (CH4).

Final answer:

The general formula for an aldehyde is R-CHO, which signifies a hydrogen (H) and a hydrocarbon (R) single bonded to a carbonyl carbon.

Step-by-step explanation:

The general formula of an aldehyde is R-CHO. An aldehyde has either two hydrogens or a hydrogen and a hydrocarbon (R) single bonded with the carbonyl carbon, symbolized as R-C-H. The condensed form of the aldehyde group is -CHO. This structure differentiates aldehydes from ketones, which are represented as R-CO-R' and have two hydrocarbon groups bonded with the carbonyl carbon.

An aldehyde has the general formula R-CHO. It consists of a carbonyl group (-C=O) with a hydrogen atom (H) and a hydrocarbon group (R) bonded to the carbon atom. For example, CH3CHO is the condensed formula for ethanal, which is a common aldehyde.
