FAQs on Chemical Bonding (Advanced) - Practice Sheet Solution, Class 11, Chemistry - JEE

1. What is chemical bonding?
Ans. Chemical bonding refers to the process by which atoms combine to form molecules or compounds. It involves the sharing or transfer of electrons between atoms to achieve a stable electronic configuration.
2. What are the different types of chemical bonds?
Ans. There are three main types of chemical bonds: covalent bonds, ionic bonds, and metallic bonds. In covalent bonds, atoms share electrons to achieve stability. Ionic bonds occur when electrons are transferred from one atom to another, resulting in the formation of positively and negatively charged ions. Metallic bonds are formed between metal atoms and involve the sharing of a sea of electrons.
3. How does a covalent bond form?
Ans. A covalent bond forms when two atoms share electron pairs. This sharing occurs due to the overlapping of atomic orbitals, resulting in the formation of a molecular orbital. Covalent bonds are typically found between nonmetal atoms and are stronger than other types of bonds.
4. What is electronegativity and how does it affect chemical bonding?
Ans. Electronegativity is a measure of an atom's ability to attract electrons towards itself in a chemical bond. It plays a crucial role in determining the type of bond formed between atoms. If the electronegativity difference between atoms is small (less than 1.7), a covalent bond is formed. If the electronegativity difference is large (greater than 1.7), an ionic bond is formed.
5. How does the octet rule relate to chemical bonding?
Ans. The octet rule states that atoms tend to gain, lose, or share electrons in order to achieve a stable electron configuration of eight valence electrons. This rule helps explain the formation of chemical bonds. Atoms may gain or lose electrons to achieve a complete outer shell, while others may share electrons to achieve an octet. The octet rule is particularly applicable to main group elements.
