FAQs on Important Question : Chemical Bonding & Molecular Structure - Class 11

1. What is chemical bonding?
Ans. Chemical bonding is the process of joining two or more atoms to form a molecule. It is the attraction between atoms that allows for the formation of chemical compounds.
2. What are the types of chemical bonds?
Ans. The types of chemical bonds are ionic bonds, covalent bonds, metallic bonds, and hydrogen bonds. Ionic bonds involve the transfer of electrons, covalent bonds involve the sharing of electrons, metallic bonds involve the sharing of electrons in a metal lattice, and hydrogen bonds involve the attraction between a hydrogen atom and an electronegative atom.
3. What is the octet rule?
Ans. The octet rule states that atoms tend to gain, lose, or share electrons in order to achieve a full outer shell of eight electrons. This is also known as the stable octet rule.
4. What is molecular geometry?
Ans. Molecular geometry is the three-dimensional arrangement of atoms in a molecule. It is determined by the number of electron pairs and the repulsion between them, which leads to different shapes such as linear, bent, trigonal planar, and tetrahedral.
5. How do intermolecular forces affect molecular structure?
Ans. Intermolecular forces are the attractive or repulsive forces between molecules that affect their physical properties such as boiling point, melting point, and solubility. They also affect molecular structure by influencing the shape and arrangement of molecules, such as in the case of hydrogen bonding in water molecules leading to a tetrahedral shape.
