When an aqueous solution of D-glucose is treated with a base, it is converted into D-fructose and D-mannose, this conversion (isomerisation) involves
1 enolisation
2 tautomerisation.
3 both (1) and (2)
4 none of these
Explanation:
When an aqueous solution of D-glucose, D-mannose or D-fructose is treated with a base, it undergoes enolisation and a series of ketoenol tautomerisation to form a mixture of the three monosaccharides (Lobry de Bruyn-van Ekenstein transformation).
