WebSep 29, 2024 · Each water molecule can form 2 hydrogen bonds between oxygen and the two hydrogen atoms in the molecule. An additional two bonds can be formed between each hydrogen atom and nearby oxygen atoms. A consequence of hydrogen bonding is that hydrogen bonds tend to arrange in a tetrahedron around each water molecule, leading to … WebHere, in H2O, O has 6 electrons in its outermost subshell (2p). That translates to 3 orbitals. 2 orbitals having 2 pairs of electrons exist as lone pairs.
