Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What type of bond is found inside of a water molecule?
A
Covalent
B
Hydrogen
C
Ionic
D
Peptide
Explanation: 

Detailed explanation-1: -In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.

Detailed explanation-2: -Water is a Polar Covalent Molecule Water (H2O), like hydrogen fluoride (HF), is a polar covalent molecule. When you look at a diagram of water (see Fig. 3-2), you can see that the two hydrogen atoms are not evenly distributed around the oxygen atom.

Detailed explanation-3: -Covalent bond and intermolecular Hydrogen bond. is present in a water molecule.

Detailed explanation-4: -Each pair of shared electrons represents one covalent bond, so two covalent bonds hold the water molecule together.

Detailed explanation-5: -A water molecule is composed of one oxygen and two hydrogen atoms that are joined together by polar covalent bonds. Covalent mean that the atoms share electrons, instead of completely giving up electrons to one another.
