The reactions of hydroxylamine with a sy...

The reactions of hydroxylamine with a symmetrical ketone `(R_(2)C = O)` froms only one oxmie. However two isomeric oximes may be formed when an aldehyde or non-symmetical ketone takes part in the reaction. Explain.

Text Solution

Verified by Experts

In an oxime. The rotation about `gtC=N` bond is restricted. In case two different atoms/group are attached to the double bonded carbon atom, geometrical isomerism is possible. For example,
