Question

Select the correct answer. Which factor causes water to form small drops on a waxy surface? A. van der Waals forces B. hydrogen bonding C. London dispersion forces D. ionic bonding

Answer 1

B. hydrogen bonding

Explanation:

Waxy surfaces are non-polar while also water is polar. There is a difference in electronegativity between the atoms O and H, in which O is more electronegative than H. Such a difference in electronegativity causes the two covalent O-H bonds to become polar in water, where O atom has a partial negative charge, and the H atom has a partial positive charge.

Therefore from the above explanation the correct answer is B
