An insect known as a water strider can walk across the surface of a pond. which of the following is the directly responsible for this insect being able to walk on the surface without sinking?

a. Ionic bonding
b. Oxygen bonding
c. Hydrogen bonding
d. Nonpolar covalent bonding

 

(C) Hydrogen bonding.

▪ Hydrogen bond causes the attraction between water molecules.

▪ Inner molecules are attracted evenly from alld irections. But surface molecules have unbalanced force caused by inner pulling. This is surface tension.

▪ Thus causes the net upward force in upper layer of water. This helps striders to walk on water.
