FAQs on Index: Chemical Bonding and Molecular Structure - Chemistry Class 11 - NEET

1. What is a chemical bond?
Ans. A chemical bond is a force of attraction that holds atoms together in a molecule. It is formed when two or more atoms share electrons or transfer electrons from one atom to another. Chemical bonds are responsible for the stability of molecules and the formation of various compounds.
2. What are the types of chemical bonds?
Ans. There are three main types of chemical bonds: covalent bonds, ionic bonds, and metallic bonds. Covalent bonds occur when atoms share electrons, while ionic bonds are formed by the transfer of electrons between atoms with opposite charges. Metallic bonds are specific to metals, where the valence electrons are delocalized and shared among a lattice of metal atoms.
3. How do covalent bonds form?
Ans. Covalent bonds form when two nonmetal atoms share electrons to achieve a stable electron configuration. Each atom contributes one or more electrons to the shared electron pair, creating a bond. The number of shared electrons varies based on the number of valence electrons in the atoms involved.
4. What is the octet rule in chemical bonding?
Ans. The octet rule states that atoms tend to gain, lose, or share electrons in order to achieve a stable electron configuration with eight valence electrons. This rule is applicable to most atoms, except for hydrogen and helium, which follow the duet rule (achieving a stable configuration with two valence electrons).
5. How does electronegativity influence bond type?
Ans. Electronegativity is a measure of an atom's ability to attract electrons towards itself in a chemical bond. The difference in electronegativity between two atoms determines the type of bond they will form. If the electronegativity difference is small (less than 1.7), a covalent bond is likely to form. If the difference is large (greater than 1.7), an ionic bond is more probable.
