The correct option is (b) RCHO
The general formula for an aldehyde is RCHO.
<h3>What is an aldehyde?</h3>
- An organic molecule with the functional group RCH=O is known as an aldehyde. The functional group alone (without the "R" side chain) can be categorized as a formyl group or as an aldehyde.
- Aldehydes are widespread and have significant functions in both the technological and biological worlds.
- Aldehydes have a carbon center attached to oxygen via a double bond, hydrogen via a single bond, and a third substituent—usually carbon or, in the case of formaldehyde, hydrogen—by a single bond. It's common to refer to the center carbon as being sp2-hybridized. Aldehydes belong to a polar category.
