The Correct Option is C

Solution and Explanation

The correct answer is option (C): Acrolein
1.The common name of CH2=CH-CHO is acrolein. Acrolein is an unsaturated aldehyde and its chemical formula is C3H4O. It has a pungent odor and is colorless to yellowish in color. 2. The chemical formula for mesityl oxide is (CH3)2C=CHC(O)CH3. It is a colorless organic compound with a pleasant peppermint-like odor. 3. Prop-2-enal has a chemical formula C3H4O. It is an unsaturated aliphatic compound with an aldehyde group. The IUPAC name is prop-2-enal. 4. Propanal-1-ene is not a valid chemical name for an IUPAC name. So, the correct answer is Acrolein.

Applications of surface chemistry are:

Adsorption:

The process of attraction and aggregation of the molecules of a substance on the surface of a solid is known as adsorption. For Example, N2 adsorbs on the surface of activated charcoal

Two types of adsorption are:-

  • Chemisorption: It is also known as Chemical Adsorption.
  • Physisorption: It is also known as Physical Adsorption.

Corrosion:

The process through which the refined metals convert themselves into more stable compounds is known as corrosion.

Crystallisation:

The type of technique used in order to purify the substances to separate Solids from liquids is known as crystallisation.

Heterogeneous Catalysis:

The process wherein a catalyst is used in order to increase the rate of a chemical reaction is known as catalysis. The catalyst does not undergo any transformation and can be recovered in a chemically unchanged state. 

There are two types of catalysis:-

  • When the catalyst involved and the reacting substances are same states of matter or in the same phase, it is known as Homogeneous Catalysis.
  • When the catalyst involved and the reacting substances are in different states of matter or different phases, it is known as Heterogeneous Catalysis.
