FAQs on Chemical Bonding and Molecular Structure JEE Main Mock Test 2025-26 Practice
1. What is chemical bonding and why is it important in chemistry?
Chemical bonding refers to the attractive forces that hold atoms together in compounds and molecules. It is crucial because it determines the structure, stability, and properties of all substances, helping explain how elements interact and form new materials in chemical reactions.
2. What are the main types of chemical bonds?
The main types of chemical bonds are:
Ionic bonds (formed by transfer of electrons),
Covalent bonds (sharing of electrons), and
Metallic bonds (delocalized electrons among metal atoms).
3. What is the octet rule, and are there any exceptions?
The octet rule states that atoms tend to gain, lose, or share electrons to achieve eight electrons in their valence shell, resembling the noble gas configuration. Exceptions include molecules with an odd number of electrons (like NO), atoms with less than an octet (like BeH2), and expanded octets for elements in period 3 or beyond (like SF6).
4. How is a Lewis structure drawn for a molecule?
To draw a Lewis structure:
1. Count all valence electrons.
2. Sketch a skeleton structure with single bonds.
3. Complete octets around outer atoms.
4. Place any remaining electrons on the central atom.
5. Use multiple bonds if needed to satisfy octets.
5. What is the VSEPR theory and how does it predict molecular shape?
VSEPR theory (Valence Shell Electron Pair Repulsion) predicts molecular geometry by assuming that electron pairs around a central atom repel each other and arrange themselves as far apart as possible, determining the shape of the molecule (e.g., linear, trigonal planar, tetrahedral).
6. What is the difference between polar and nonpolar molecules?
Polar molecules have an unequal distribution of electron density, resulting in partial positive and negative charges (dipole moment), while nonpolar molecules have a symmetrical electron distribution and no net dipole moment.
7. Explain the concept of hybridization with an example.
Hybridization is the mixing of atomic orbitals to form new hybrid orbitals suitable for bonding. For example, in CH4 (methane), the carbon atom undergoes sp3 hybridization, forming four equivalent sigma bonds with hydrogen.
8. What is resonance, and why does it occur?
Resonance occurs when a molecule cannot be represented by a single Lewis structure and exists as a hybrid of two or more structures. It helps explain bond length and stability in molecules like ozone (O3) and benzene (C6H6).
9. How can you determine if a compound is ionic or covalent?
A compound is likely ionic if it forms between a metal and a nonmetal with a large electronegativity difference (>1.7). If it forms between two nonmetals with similar electronegativity, it is usually covalent.
10. What is the significance of molecular geometry in chemical properties?
Molecular geometry influences the physical and chemical properties of substances, including solubility, polarity, reactivity, and intermolecular forces. The 3D arrangement of atoms determines how molecules interact with each other.
11. What is a coordinate (dative) bond?
A coordinate bond, also known as a dative covalent bond, occurs when both bonding electrons are donated by the same atom, often seen in complexes like NH4+ or CO.
12. What are the experimental techniques to determine molecular structure?
Molecular structures are commonly determined by:
- X-ray crystallography
- Electron diffraction
- Spectroscopy (infrared, Raman)
These methods provide data on bond lengths, bond angles, and 3D arrangements of atoms.
