please complete question 1

EXERCISE 26 (continued) so that the COOH and the H and OH cid enantiomers and Position the models so that they appear as mirror images. Arrange them so that the group is on the top and the CH, is on the bottom of the chiral carbon atom, and the are coming toward you. Now draw projection structures of the two lactic acid enant observe that they are mirror images. Question 1. One criterion for an organic compound to show optical activity is that the pound has at least one chiral carbon atom. Circle any of the following compounds that will show optical activity.

Answer 1

Lactic acid is an organic acid. It has a molecular formula CH₃CH(OH)COOH. It is white in solid-state and it is miscible with water. Lactic acid is chiral, consisting of two enantiomers.

An asymmetric carbon atom (chiral carbon) is a carbon atom that is attached to four different types of atoms or groups of atoms.
