b) The total number of hydrogen bonds in CH₄ are: 4The total number of hydrogen bonds in H₂O are: 2.CH₄ is called as Methane.
It is colorless, odorless, flammable gas that is the simplest hydrocarbon and is the major constituent of natural gas.CH₄ consists of 4 covalent bonds between these five atoms.
Covalent bonds are the bonds which involves the sharing of electrons to form electron pairs between atoms.
They have the same electronegativities. H₂O consist of polar covalent bond.
As it is a polar covalent molecule. A polar covalent bond occurs when atoms are shared unequally in a covalent bond.
The atoms do not have the same electronegativities.
