A single water molecule can make three to four hydrogen bonds. A single water molecule can usually make three hydrogen bonds but in some cases it can make up to four.
Hint: If your high school Biology teacher is asking you this question the number of hydrogen bonds a molecule of water can make is almost always three (just remember one bond for each element).
hydrogen can form 4 bonds with a molecule of water due to presence of a pair of lone pairs on oxygen atom.
Three. One bond oxygen to hydrogen, two bonds hydrogens to oxygen's.
the formula is H2O
Hydrogen atoms 2
oxygen atoms 1

A water molecule can form two hydrogen bonds, both hydrogen atoms can be involved.
four
2 covalent bonds
ONE double bond (eg. in oxygen O2: O=O) or TWO single bonds (eg. in water H2O: H-O-H).
C-C sigma bonds in acetone : 2 C-H bonds in water : 0 C-O bonds in water : 0 C-O sigma bonds in propanol : 1 C-C pi bonds in methanol : 0
Because of the presence of two lone pairs on Oxygen and due to polarity of the two Hydrogens, H20 can form 4 Hydrogen bonds. Bollaram Dileep Kumar
No ethane (C2H6) is a hydrocarbon and hydrocarbons can't form hydrogen bonds. Only molecules containing hydrogen (H) bonded with nitrogen (N), oxygen (O) or fluorine (F) can form hydrogen bonds.
2 covalent bonds
ONE double bond (eg. in oxygen O2: O=O) or TWO single bonds (eg. in water H2O: H-O-H).
2H2 + O2 + 2H2O 2H-H + O=O = 2H-O-H..not shaped like this !! The bonds in the reactants break and the bonds in the products form. The bonds in the H2 and O2 break and the bonds in the water form.
C-C sigma bonds in acetone : 2 C-H bonds in water : 0 C-O bonds in water : 0 C-O sigma bonds in propanol : 1 C-C pi bonds in methanol : 0
Yes, H-bonds are weak bonds. The hydrogen bond is approximately 30 times weaker than a normal covalent bond.
2 covalent bonds: H-O-H. In other words, it makes water.
H+ +H2O=H3O+ It bonds to water
One molecule of water (H-O-H) contains two ionic bonds.
polarity ionic bonds h bonds
Because of the presence of two lone pairs on Oxygen and due to polarity of the two Hydrogens, H20 can form 4 Hydrogen bonds. Bollaram Dileep Kumar
All four C-H bonds in methane are broken during combustion.
