Question
Chapter 24.17, Problem 20P
Interpretation Introduction
Interpretation:
The two alditols that are produced when
Concept introduction:
The sodium borohydride or lithium aluminum hydride or catalytic hydrogenation is used to reduce carbonyl groups in carbohydrates.
The product of the reduction reaction of ketose or aldose yields alditols.
Alditols lack the carbonyl group and exist entirely in open chain form.
