Assertion (A): All naturally occurring \(\alpha\)-amino acids except glycine are optically active. Reason (R): Most naturally occurring amino acids have L-configuration.
Assertion (A) is false, but Reason (R) is true.
Step 1: Understanding optical activity of amino acids. All naturally occurring \(\alpha\)-amino acids, except for glycine, are optically active because they contain a chiral carbon atom (except glycine, which has two hydrogen atoms on the chiral center, making it achiral).
Step 2: L-configuration of amino acids. Most naturally occurring amino acids are in the L-configuration, which is why they are optically active (except glycine).
Step 3: Conclusion. Thus, both Assertion (A) and Reason (R) are true, and Reason (R) correctly explains Assertion (A), making option (A) the correct answer.
(a) Define the following:
(i) Enantiomers
(ii) Racemic mixture
The CORRECT statement(s) regarding the given molecules is(are):
How many different stereoisomers are possible for the given molecule?
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.
