Solution and Explanation
(I) Ethyl benzoate and benzoic acid can be distinguished using an ester hydrolysis test. Ethyl
benzoate undergoes hydrolysis in the presence of an acid or base to form benzoic acid and
ethanol, while benzoic acid remains unchanged.
(II) Propanal and propanone can be distinguished using a mild oxidizing agent like Tollens’ reagent. Propanal will be oxidized to form an acid (propanoic acid), while propanone will not react with Tollens’ reagent.
(II) Propanal and propanone can be distinguished using a mild oxidizing agent like Tollens’ reagent. Propanal will be oxidized to form an acid (propanoic acid), while propanone will not react with Tollens’ reagent.

- Carbohydrates are polyhydroxy aldehydes or ketones that represent enormous structural diversity in terms of the arrangement of atoms in space, resulting in hundreds of stereoisomers. Although the chemical properties of most stereoisomers may not be very different, their metabolic rate and utilization in biological systems is significantly different and known to influence the overall carbohydrate metabolism. Structural variants, which arise due to a different arrangement of atoms in three-dimensional space are known as stereoisomers. The number of stereoisomers can be theoretically estimated by using the formula 2n, where ‘n’ is the number of stereocenters or asymmetric (chiral) carbon atoms in a molecule. Out of these stereoisomers, there are some structures, which are mirror images of each other, and they are referred to as enantiomers.

Rupal, Shanu and Trisha were partners in a firm sharing profits and losses in the ratio of 4:3:1. Their Balance Sheet as at 31st March, 2024 was as follows:
(i) Trisha's share of profit was entirely taken by Shanu.
(ii) Fixed assets were found to be undervalued by Rs 2,40,000.
(iii) Stock was revalued at Rs 2,00,000.
(iv) Goodwill of the firm was valued at Rs 8,00,000 on Trisha's retirement.
(v) The total capital of the new firm was fixed at Rs 16,00,000 which was adjusted according to the new profit sharing ratio of the partners. For this necessary cash was paid off or brought in by the partners as the case may be.
