In the network structure of ice, what is the average maximum number of hydrogen bonds that a single water molecule can form?

Answer

Four

Each water molecule can function as both a hydrogen bond donor (via its two O-H bonds) and an acceptor (via its two lone pairs), enabling an average of four hydrogen bonds per molecule in its network.
