The sequence of increasing van der Waals radii for the elements O, N, Cl, F, and Ne is:

1. F, O, N, Ne, Cl
2. Ne, F, O, N, Cl
3. F, Cl, O, N, Ne
4. N, O, F, Ne, Cl

Correct answer: F, O, N, Ne, Cl

Solution

The van der Waals radii increase in the order F < O < N < Ne < Cl due to the increase in atomic size and electron cloud, making F, O, N, Ne, Cl the correct sequence.
