Given below are two statements, one is labelled as Assertion $A$ and the other is labelled as Reason R
Assertion A : Butylated hydroxy anisole when added to butter increases its shelf life
Reason R : Butylated hydroxy anisole is more reactive towards oxygen than food
In the light of the above statements,choose the most appropriate answer from the options given below
Assertion A : Butylated hydroxy anisole when added to butter increases its shelf life
Reason R : Butylated hydroxy anisole is more reactive towards oxygen than food
In the light of the above statements,choose the most appropriate answer from the options given below
- $A$ is correct but $R$ is not correct
- Both $A$ and $R$ are correct but $R$ is NOT the correct explanation of $A$
- A is not correct but $R$ is correct
- Both $A$ and $R$ are correct and $R$ is the correct explanation of $A$
The Correct Option is D
Solution and Explanation
Assertion A is true - adding butylated hydroxyanisole (BHA) to butter increases its shelf life by acting as an antioxidant.
Reason R is also true and explains why Assertion A is true - BHA is more reactive towards oxygen than food, and it acts as an antioxidant by preventing the oxidation of fats in the butter, which helps in extending its shelf life.
Butylated hydroxyl anisole is an antioxidant.
So, the correct answer is (D): Both A and R are correct and R is the correct explanation of A

Concepts Used:
Chemistry in Everyday Life
The scientific study of matter’s properties and behaviour is known as chemistry. It is a natural science that studies the elements that makeup matter, as well as the compounds, made up of atoms, molecules, and ions: their composition, structure, qualities, and behaviour, as well as the changes that occur when they mix with other things.
- Importance of Chemistry in Food - Chemicals are the fundamental components of everything. Chemical molecules make up all food, including carbs, vitamins, lipids, proteins, and fibre, which are all safe and often desirable.
- Importance of Chemistry in Medicines - Medicines or pharmaceuticals are chemical substances that are used to treat diseases and relieve pain. Chemistry has made significant contributions to health care. Chemistry, for example, aids in the manufacture and application of surgical materials.
- Importance of Chemistry in Cosmetics - In our daily lives, we use lotions, fragrances, talcum powder, and a variety of other cosmetic goods. All of these items are developed in laboratories using chemicals for our health and skin.
- Importance of Chemistry in Soaps and Detergents - Soaps are sodium and potassium salts of fatty acids with greater molecular weights, such as stearic acid, palmitic acid, and oleic acid. Sodium salts of long-chain alkyl hydrogen sulphates or sodium salts of long-chain alkyl benzene sulphonic acids are commonly used as detergents.
