2-chlorobutane contains one chiral center, leading to two optical isomers (enantiomers).
Assertion (A): All naturally occurring \(\alpha\)-amino acids except glycine are optically active. Reason (R): Most naturally occurring amino acids have L-configuration.
(a) Define the following:
(i) Enantiomers
(ii) Racemic mixture
The CORRECT statement(s) regarding the given molecules is(are):
A force \( \vec{f} = x^2 \hat{i} + y \hat{j} + y^2 \hat{k} \) acts on a particle in a plane \( x + y = 10 \). The work done by this force during a displacement from \( (0,0) \) to \( (4m, 2m) \) is Joules (round off to the nearest integer).
