In organic chemistry, an aldehyde is an organic compound containing a functional group with the structure R−CH=O. The functional group itself (without the "R" side chain) can be referred to as an aldehyde but can also be classified as a formyl group. Aldehydes are common and are important in technology and … See more Aldehydes feature a carbon center that is connected by a double bond to oxygen and a single bond to hydrogen and a single bond to a third substituent, which is carbon or, in the case of formaldehyde, hydrogen.

WebR – CH2 – OH → R – CHO. PCC (Pyridinium chlorochromate) is the most suitable reagent for the above conversion, because it oxidises primary alcohol to aldehydes and secondary alcohols to ketones. It will not affect any other functional group. So it has high selectivity for the oxidation of alcohols. Hence option (2) is the answer. WebEsters (R-CO-O-R’) are named as alkyl derivatives of carboxylic acids. The alkyl (R’) group is named first. The R-CO-O part is then named as a separate word based on the carboxylic acid name, with the ending changed from -oic acid to -oate. For example, CH 3 CH 2 CH 2 CH 2 COOCH 3 is methyl pentanoate, and (CH 3) 2 CHCH 2 CH 2 COOCH 2 CH 3 ...

WebAldehydes (-R-CHO): An aldehyde is an organic compound in which a C-atom is double-bonded to an O-atom on one side and a hydrogen (H) atom on the other. Acetaldehyde is the simplest aldehyde with the formula CH 3 CHO. Ketones (-R-CO-R): In ketones, the carbon-carrying double-bonded O-atom is bonded to two other C-atoms or alkyl chains at the sides.
