Question

Wilhem Ostwald redefined the action of
A. Anamers
B. Isomers
C. Catalyst
D. Geometry of monomers

Answer 1

Hint: A philosopher and scientist from Germany's Baltic region, Wilhelm Ostwald. Along with Jacobus Henricus van 't Hoff, Walther Nernst, and Svante Arrhenius, Ostwald is recognised as one of the pioneers of the subject of physical chemistry.

Complete Step by Step Solution:
A philosopher, Wilhelm Ostwald is known as one of the pioneers of physical chemistry that we study today. His major achievement came when he discovered the role of the catalyst. The role of the catalyst was reinterpreted by Wilhelm Ostwald.

He researches the velocities and rates of acid and basic chemical reactions.
He discovered that the amount of acid or base present in a particular chemical reaction has a significant impact on how quickly the reaction proceeds.

A catalyst, according to Ostwald, is a material that speeds up a chemical reaction without being a component of the reactants or the products.
Option B is wrong since isomers have the same number of atoms or chemical formula but distinct spatial arrangements of those atoms.
Option A is incorrect because anomers are cyclic monosaccharides or glycosides that are epimers.
Option D is wrong since a monomer is a molecule from any class of chemical that has the ability to interact with other molecules to create polymers, which are long-chain compounds.
Hence, the correct option is C. catalyst.

Note: The thing to note here in order to solve the question, are the contributions of Wilhem Ostwald and the fields in which he has contributed. Since, he had researched about the rate of reactions and redefined the action of catalysts in a much more acceptable way.
