(iii) The negative charge that rests on the electronegative O atom in carboxylate ion.
. Methods of Preparation of Monocarboxylic Acids. For the same reason RCOOâ is more stable than the phenoxide ion where the oxygen has no negative charge on it. Aliphatic aldehydes are more reactive than ketones because of the following reasons : Inductive effect : Alkyl groups are electron donating in nature (i.e., show +I-Effect ). An organic compound contains 69.77% carbon, 11.63% hydrogen and rest, oxygen.

The boiling point of aldehydes and ketones are higher than hydrocarbons and ethers of comparable molecular mass due to high magnitude of dipole-dipole interactions. (b) Similarly, Ka values of methyl-substituted (toluic acids) at 298 K are as follows: From the Ka values, it is evident that with the exception of o-isomer, both p and m-toluic acids are weaker acids than benzoic acid whereas the three isomeric nitro benzoic acids are stronger acids than benzoic acid. ,carbonyl groups in the presence of base.
