Alkanes are almost non-polar molecules because of the covalent nature of C—C and C—H bonds and due to very little difference of electronegativity between carbon and hydrogen atoms. They possess weak Van Der Waals forces. Due to the weak forces, the first four members C1 to C4 are gases, C5 to C17 are liquids and those containing 18 carbon atoms or more are solids at 298K. They are colourless and odourless. In alkanes, there is a steady increase in boiling point with the increase in molecular mass. This is due to the fact that the intermolecular Van Der Waals forces increase with increase of the molecular size or the surface area of the molecule. With the increase in branching, the boiling point of alkanes decreases. The given questions (i) to (iv) consist of an assertion (A) and reason (R) statement. Choose the appropriate answer.
Assertion: The first four members of alkanes are gases.
Reason: They possess weak Van Der Waals forces.
- a)A and R both are correct and R is the correct explanation of A.
- b)A and R both are correct but R is not the correct explanation of A.
- c)A is true but R is false.
- d)A is false but R is true.
Correct answer is option 'A'. Can you explain this answer?

Alkanes are almost non-polar molecules because of the covalent nature...
Assertion: The first four members of alkanes are gases.
The first four members of alkanes, namely methane (CH4), ethane (C2H6), propane (C3H8), and butane (C4H10), are indeed gases at room temperature.
Reason: They possess weak Van Der Waals forces.
The weak Van Der Waals forces present in alkanes contribute to their non-polar nature, which makes them gases at room temperature. These weak forces are a result of the covalent nature of C—C and C—H bonds, as well as the minimal difference in electronegativity between carbon and hydrogen atoms.
Therefore, both the assertion and the reason are correct in this case. The weak Van Der Waals forces in alkanes are responsible for the low boiling points of the first four members, leading to their gas state at room temperature. Hence, the correct answer is option 'A.'
