Aldehydes, Ketones and Carboxylic Acids Class 12 Notes – Chapter 12
Some important organic compounds containing carbonyl group are carboxylic acids, aldehydes, and ketones. These molecules are highly polar and hence have high boiling temperatures when compared to hydrocarbons as well as weak polar compounds such as ethers of comparable molecular masses. The lower embers form hydrogen bonds with water and therefore are highly water soluble.
On the other hand, higher members have big size hydrophobic carbon chain and are insoluble in water. Method of preparing aldehyde is by controlled oxidation of primary alcohols or dehydrogenation and cautious or controlled reduction of acyl halides.
