Question

Why MnO is basic while NO is neutral?
Also clarify the oxidation state of NO?

Answer 1

metal oxides are basic in nature

non metal oxides are acidic in nature

so MnO yes metal oxide which is basic.

whereas. Neutral oxides are those oxides which show neither basic nor acidic properties when they react with water. Examples include carbon monoxide (CO) and nitrous oxide (N2O) which are only slightly soluble in water, and nitric oxide (NO) which is appreciably soluble in cold water.
