प्रश्न
Explain the nature of the covalent bond using the bond formation in CH3Cl.
उत्तर
The structure of CH3Cl is given below:
The molecule of chloromethane (CH₃Cl) is made up of three elements: carbon (Z = 6), hydrogen (Z = 1), and chlorine (Z = 17). Carbon has four valence electrons (2, 4), hydrogen has one (1), and chlorine has seven valence electrons (2, 8, 7). To achieve a full octet, carbon shares three of its valence electrons with three hydrogen atoms, and the fourth electron is shared with the chlorine atom.

A compound in which two Covalent bonds are formed.
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.
