BIOMOLECULES AND ENZYMES

Detailed explanation-1: -GEOMETRICAL ISOMERISM IN OXIMES The oximes are of two types: 1) Aldoximes: These are derived from aldehydes. In this case, at least either R or R1 is hydrogen. 2) Ketoximes: These are derived from ketones.

Detailed explanation-2: -Geometrical isomerism occurs where atoms or groups are arranged uniquely in space due to the limited rotation of bonds or bonds in a molecule. Due to the minimal rotation of the C = N bond, the oxymes exhibit geometrical isomerism. To differentiate them, the descriptors, syn, and anti, are used.

Detailed explanation-3: -<br> Reason: Oximes of aldehydes and ketones show geometrical isomerism.

Detailed explanation-4: -In aldoximes, the isomer is named as syn if hydrogen and hydroxyl groups are on the same side of C=N bond and if these are on opposite sides, the isomer is named as anti. In ketoximes, the prefixes syn and anti indicate which group of ketoxime is syn or anti to hydroxyl group.
