Explanation:
Sulphuric acid (H2SO4) is a strong mineral acid with numerous properties. Let's analyze each option to determine which one is not a property of sulphuric acid.
a) It acts as a strong dehydrating agent:
Sulphuric acid is known for its strong dehydrating properties. When it reacts with certain compounds, it can remove water molecules from them, leading to dehydration. This property is widely used in industries, laboratories, and various chemical processes.
b) It is a Lewis acid:
A Lewis acid is a substance that can accept an electron pair to form a covalent bond. Sulphuric acid can act as a Lewis acid in certain reactions, where it accepts an electron pair and forms a coordinate bond. Therefore, sulphuric acid can indeed function as a Lewis acid.
c) It cannot char carbohydrates:
This statement is incorrect. Sulphuric acid has the ability to char carbohydrates. When concentrated sulphuric acid comes into contact with carbohydrates, such as sugar or cellulose, it can cause their decomposition and ultimately lead to the formation of carbon or charred residue.
d) It is dense and oily:
Sulphuric acid is a dense liquid with a high viscosity, giving it the appearance of being oily. It is not actually an oil, but due to its properties, it can have a similar visual appearance.
Therefore, the correct answer is option 'c' - "It cannot char carbohydrates." This statement is incorrect as sulphuric acid can indeed char carbohydrates through its strong acidic and dehydrating properties.
