Which of the following statements about carboxylic acids is/are correct? 1. Simple aliphatic carboxylic acids are soluble in water. 2. Higher carboxylic acids are practically insoluble in water. 3. The acidity of a carboxylic acid depends on the number of carbon atoms present in the hydrocarbon chain. Select the correct answer using the code given below. Correct Answer 1, 2 and 3

The correct answer is 1, 2 and 3.

Explanation:

Carboxylic Acids:

  • Carboxylic acid is an organic compound that contains the carboxyl group -COOH.
  • The general formula of a carboxylic acid is R-COOH, where R refers to the alkyl group.
  • E.g: Amino acids, Fatty acids.
  • The acidity of a carboxylic acid depends on the number of carbon atoms present in the hydrocarbon chain. Hence, statement 3 is correct.
  • The acids with less than 5 carbon atoms are easily soluble in water but acids with a greater number of carbon atom or acids with more molecular weight are not soluble in water because of the presence of large hydrocarbon portion in the molecule. Hence, statements 1 and statement 2 are correct.

Which option is correct about IUPAC nomenclature for branched-chain saturated hydrocarbon? The longest chain of carbon atoms in the structure of the compound is found first. The position of the alkyl group is indicated by writing the number of carbon atoms to which it is attached.
Which option is correct about IUPAC nomenclature for branched-chain saturated hydrocarbon? The alkyl group present as side chains are considered as substituents and named separately as methyl or ethyl groups. The carbon atoms of the longest carbon chain are numbered in such a way that the alkyl groups get the lowest possible number.

In a batch process, the reaction takes place in the presence of an acid medium. The acid is drained from the reaction vessel at the rate of 15ml/s as a result of the density difference of the acid from the reacting component. To avoid wastage of acid, it is recycled to an acid tank which has 1000 L capacity. The acid drained from the reaction vessel, picks up 50 g/L solids from the reactor. Acid is fed once again to the process from acid tank. When the process is started, the acid is almost pure in the tank as a result of filtration. As the reaction proceeds, acid in the tank gets more and more contaminated with the solids. The concentration of the solids should not exceed 100 g/L from the process point of view. The batch time is 16h. Estimate whether the concentration of the solids will exceed 100g/L during the batch reaction.
