Well you have to consider how many it can "donate" and how many it can "accept". According to wikipedia water can form four. So considering methanol, the delta positive hydrogen can from one H-bond and the the two lone pairs on the oxygen can form one each. So it can form three hydrogen bonds.
Don't worry about the hydrogens on the carbon they don't take part.
Carbon will form four covalent bonds, nitrogen will form three covalent bonds, oxygen will form two covalent bonds, and hydrogen will form one covalent bond. Click on the related link to see a diagram showing the structure of an amino acid.
Oxygen doesn't have any hydrogen bonds. A hydrogen bond is when a hydrogen atom is bonded with an electronegative atom, such as oxygen. Oxygen all by itself does not have hydrogen bonded to it. It is simply written as 02.
Ammonia can form four hydrogen bonds per molecule. The lone pair on nitrogen can accept one hydrogen to form a hydrogen bond, and the three hydrogen atoms can bond to lone pairs to form three additional hydrogen bonds. However, if ammonia is the only molecule present, this bonding pattern is problematic because each molecule only has one lone pair per three hydrogen atoms. Thus, an average molecule would likely only have two hydrogen bonds, out of the maximum of four.
Alcohol can form hydrogen bonds through the hydroxyl (–OH) group. Each hydroxyl group can potentially form one hydrogen bond with another molecule or functional group that contains an available hydrogen bond donor or acceptor.
No, chlorine cannot form hydrogen bonds because it does not have any hydrogen atoms directly bonded to it. Hydrogen bonds form between hydrogen atoms and other electronegative atoms like oxygen, nitrogen, or fluorine.
Selenium can form two bonds with hydrogen.
Selenium can form two bonds with hydrogen.
Silicon has 4 bonds with hydrogen
Hydrogen can form one bond in a molecule.
Each hydrogen can form one bond with selenium. Each selenium atom can form two bonds, one with each hydrogen (2 hydrogen atoms total).
Silicon has 4 bonds with hydrogen

H3O, Hydronium ion, has a total of three hydrogen bonds. These are single bonds from hydrogen to oxygen and form cation with +1 charge.
A hydrogen atom can form a maximum of one covalent bond.
Hydrogen peroxide (H2O2) can form two hydrogen bonds. Each oxygen atom in the molecule can act as a hydrogen bond acceptor, allowing for two potential hydrogen bonds to form with other molecules or within the H2O2 molecule itself.
