(a) Interpretation: A sequence of reactions used in the conversion of D − galactopyranose to ethyl 2 , 3 , 4 , 6 − tetra − O − methyl − D − galactopyranoside is to be stated Concept introduction: Carbohydrates are a class of organic compounds. They can be present in the form of open chains or ringsThey are usually an aldehyde or ketone with additional hydroxyl groups. They have the general molecular formula, ( CH 2 O ) n . The six-membered ring form of carbohydrates is termed as pyranose. The five-membered ring form of carbohydrates is termed as furanose. The pyranoses can be classified as α or β based upon the configuration at the anomeric carbon. The anomeric carbon is the one which was a part of the carbonyl group in the straight-chain structure of the carbohydrate.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.
