What is the equation for the reaction between a carbonyl compound and brady's reagent?

The reaction between a carbonyl compound and Brady's reagent involves the addition of Brady's reagent (2,4-dinitrophenylhydrazine) to the carbonyl group, resulting in the formation of a yellow to orange precipitate. The reaction can be represented as R2C=O + 2,4-dinitrophenylhydrazine -> R2C=NNHC6H3(NO2)2 + H2O.

What is the opposite of a limiting reagent?

The opposite of a limiting reagent is an excess reagent. While a limiting reagent is the reactant that is completely consumed first in a chemical reaction, thereby determining the maximum amount of product that can be formed, the excess reagent is present in a greater quantity than needed to fully react with the limiting reagent. As a result, some of the excess reagent remains unreacted after the reaction is complete.
