Which of the following statement(s) is(are) true?
Options
- AOxidation of glucose with bromine water gives glutamic acid
- BThe two six-membered cyclic hemiacetal forms of D - + - glucose are called anomers
- CHydrolysis of sucrose gives dextrorotatory glucose and levorotatory fructose
- DMonosaccharides cannot be hydrolysed to give polyhydroxy aldehydes and ketones
Correct answer
B. The two six-membered cyclic hemiacetal forms of D - + - glucose are called anomers
Step-by-step solution
→ Glucose → [ 0 ] Br 2 -H 2 O Glycolic acid → ∝ - Δ - Glucose and β - D Glucose → Hydrolysis of sucrose given dextrorotatory glucose and levorotatory fructose, → Monosaccharide cannot be hydrolyzed to give polyhydroxy aldehyde and ketones.
