Question

1. which type of bonds hold two or more water molecules together, as shown? a. covalent bonds b. van der waals forces c. hydrogen bonds d. ionic bonds

Explanation:

Hydrogen bonds occur when a hydrogen atom covalently bonded to a highly electronegative atom (such as oxygen in water) is attracted to another electronegative atom. In water (\(H_2O\)), the oxygen is electronegative. The partially positive hydrogen of one water molecule is attracted to the partially negative oxygen of another water molecule, forming a hydrogen bond. Covalent bonds (A) are within a single water molecule (between \(H\) and \(O\) in \(H - O - H\)). Van der Waals forces (B) are weaker, more general intermolecular forces. Ionic bonds (D) involve the transfer of electrons between atoms (not the case in water - water attraction).

Answer:

C. hydrogen bonds
