Lactic acid, `CH_(3)CHOH.COOH` exists in two optically active forms. Explain.

Two possible stereostructures of CH_(3)CHOH.COOH , which are optically active, are called:

Two possible stereostructures of CH_(3)CHOH.COOH , which are optically active, are called:

Lactic acid (2-hydroxypropanoic acid) is an optically active compound. It can be made optically inactive by

All monosaccharides exhibit optical activity. Explain.

Tartaric acid [HO_(2)CCH(OH)CH(OH)CO_(2)H] was an important compound in history of stereochemistry. Two naturally occuring forms of tartaric acid are optically inactive. One optically inactive form (P) has a melting point of 210- 212^(@) C and can be separated into two optically acitve forms, whereas other optically inactive form (Q) cannot be resolved further. Optically inactive form Q is

Consider the three solutions of 1 M concentration 1. Sodium acetate (CH_3COONa) 2. Acetic acid + Sodium acetate (CH_3COOH+CH_3COONa) 3. Acetic acid (CH_3COOH) The pH of these solutions will be lie in the following sequence

Discuss the optical isomerism of lactic acid.

Is 1-hydroxypropanoic acid optically active ?

CH_(3)COOH_(2)^(+) , is present in the solution of acetic acid in

Glycine exists as H_3N^(+)CH_(2)COO^(-) while anthra-nilic acid, p-NH_2-C_6H_4COOH does not exist as dipolar ion.
