In an ice crystal, each water molecule is hydrogen bonded to _____ neighbouring molecules.

Answer: 4

Solution

In the ice crystal structure (hexagonal ice Ih), each water molecule forms four hydrogen bonds with neighboring water molecules in a tetrahedral arrangement. Two hydrogen bonds are formed through its two hydrogen atoms (as donor), and two through its two lone pairs on oxygen (as acceptor).
