FAQs on Short Tricks: Shapes of Molecules Video Lecture - Chemistry Class 11 - NEET

1. What are the different shapes of molecules?
Ans. Molecules can have various shapes such as linear, bent, trigonal planar, tetrahedral, and octahedral, among others. These shapes depend on the arrangement of atoms and the bonding patterns within the molecule.
2. How do you determine the shape of a molecule?
Ans. The shape of a molecule can be determined by its electron pair geometry and molecular geometry. The electron pair geometry considers both bonding and non-bonding electron pairs, while the molecular geometry only considers the arrangement of bonded atoms.
3. What is the significance of knowing the shape of a molecule?
Ans. Knowing the shape of a molecule is important as it helps in understanding its physical and chemical properties. It provides insights into the molecule's polarity, reactivity, and interactions with other molecules or ions.
4. How does molecular shape affect polarity?
Ans. The molecular shape determines the distribution of charge within a molecule. If a molecule has a symmetrical shape, it is usually nonpolar, whereas an asymmetrical shape results in a polar molecule. This polarity affects the molecule's solubility, boiling point, and ability to form intermolecular forces.
5. Can the shape of a molecule change?
Ans. The shape of a molecule can change under certain conditions. For example, some molecules can undergo molecular distortions due to the presence of lone pairs or external factors such as temperature or pressure. Additionally, chemical reactions can also lead to changes in molecular shape.
