प्रश्न
Explain the following:
Water is a polar covalent molecule.
Advertisements
उत्तर
This means that in the water molecule, one side is positively charged and the other side is negatively charged. Since the water molecule (comprising two atoms of Hydrogen and one of Oxygen) is formed by covalent bonds, the electrons are shared.
This sharing causes the electrons to stay closer to the oxygen atom giving it a slight negative charge while the hydrogen atoms, as a consequence, have a slight positive charge.

Identify the incorrect statement and correct them.
- Like covalent compounds, coordinate compounds also contain charged particles (ions). So they are good conductors of electricity.
- Ionic bond is a weak bond when compared to Hydrogen bond.
- Ionic or electrovalent bonds are formed by mutual sharing of electrons between atoms.
- Loss of electrons is called Oxidation and gain of electron is called Reduction.
- The electrons which are not involved in bonding are called valence electrons.
