FAQs on Sp Hybridisation Video Lecture - Physical Chemistry for NEET

1. What is sp hybridisation and how does it occur?
Ans. Sp hybridisation is a type of hybridisation that occurs when one s orbital and one p orbital combine to form two equivalent hybrid orbitals. This process typically occurs in atoms that form linear molecules, resulting in a bond angle of 180 degrees. Common examples include acetylene (C2H2) and carbon dioxide (CO2).
2. What are the characteristics of sp hybridised compounds?
Ans. Compounds with sp hybridisation exhibit a linear geometry with a bond angle of 180 degrees. They have two sigma bonds and no lone pairs of electrons in the hybridised orbitals. Additionally, sp hybridised atoms often show significant acidity or reactivity due to the high s character (50%) in the hybrid orbitals.
3. Can you provide examples of sp hybridised molecules?
Ans. Yes, common examples of sp hybridised molecules include acetylene (C2H2), carbon dioxide (CO2), and hydrogen cyanide (HCN). In these molecules, the central atom uses sp hybridised orbitals to form strong sigma bonds with other atoms.
4. How does sp hybridisation affect the properties of molecules?
Ans. Sp hybridisation influences the physical and chemical properties of molecules by determining their geometry and bond angles. The linear arrangement minimizes steric hindrance, leading to increased stability. Additionally, the high s character in sp hybridised bonds results in stronger and shorter bonds compared to those formed by only p orbitals.
5. What is the significance of knowing about sp hybridisation in chemistry?
Ans. Understanding sp hybridisation is crucial in predicting the geometry, reactivity, and properties of organic and inorganic compounds. It helps chemists design molecules with specific characteristics for applications in fields such as materials science, pharmaceuticals, and catalysis.
