Concept explainers
(a)
Interpretation:
Hemiacetal C should be identified and that should be label as either a or β anomer.
Concept Introduction:
Hemi-acetal is a C atom which connected to two different O atoms. One O atom is in alcohol form and the other one connected to another C atom.
Anomer C-Type of C atoms that are not stereo-genic in linear form, but stereo-genic in cyclic form. stereo-genic center can be classified as either a or β. If the -OH group is located upwards, it is β anomer and if -OH group is located downwards it is a anomer.
(b)
Interpretation:
Hemiacetal C should be identified and that should be label as either a or β anomer.
