Answer 1

CONCEPT:

Density of Benzene

Benzene is a hydrocarbon with the molecular formula C₆H₆.
It is less dense than water, which has a density of approximately 1 g/cm³.
The density of benzene is approximately 0.876 g/cm³.
Density is a physical property that compares mass per unit volume of substances.

EXPLANATION:

Water has a higher density (1 g/cm³) compared to benzene (0.876 g/cm³).
Benzene floats on water because it is less dense.
While alkanes and alkenes may also have densities lower than benzene, the correct comparison in this context is with water.
Thus, benzene is specifically less dense than water, making option 2 the correct answer.

Therefore, benzene is less dense than water (option 2).
