The correct Answer is:
To determine which hybrid orbital has only 20% d character, we will analyze the hybridization of the given compounds and calculate the percentage of d character for each. ### Step-by-Step Solution: 1. **Identify the Compounds**: The compounds given are CCl4, SF6, SF4, and Cl2O. 2. **Analyze CCl4**: - **Central Atom**: Carbon (C) - **Valence Electrons**: 4 (from carbon) - **Bond Pairs**: 4 (with 4 chlorine atoms) - **Lone Pairs**: 0 - **Steric Number**: 4 (0 lone pairs + 4 bond pairs) - **Hybridization**: sp³ - **d Character**: 0% (since sp³ has no d orbitals) 3. **Analyze SF6**: - **Central Atom**: Sulfur (S) - **Valence Electrons**: 6 (from sulfur) - **Bond Pairs**: 6 (with 6 fluorine atoms) - **Lone Pairs**: 0 - **Steric Number**: 6 (0 lone pairs + 6 bond pairs) - **Hybridization**: sp³d² - **d Character Calculation**: - Number of d orbitals = 2 - Total orbitals = 6 - % d character = (2/6) × 100 = 33.33% 4. **Analyze SF4**: - **Central Atom**: Sulfur (S) - **Valence Electrons**: 6 (from sulfur) - **Bond Pairs**: 4 (with 4 fluorine atoms) - **Lone Pairs**: 1 - **Steric Number**: 5 (1 lone pair + 4 bond pairs) - **Hybridization**: sp³d - **d Character Calculation**: - Number of d orbitals = 1 - Total orbitals = 5 - % d character = (1/5) × 100 = 20% 5. **Analyze Cl2O**: - **Central Atom**: Oxygen (O) - **Valence Electrons**: 6 (from oxygen) - **Bond Pairs**: 2 (with 2 chlorine atoms) - **Lone Pairs**: 2 - **Steric Number**: 4 (2 lone pairs + 2 bond pairs) - **Hybridization**: sp³ - **d Character**: 0% (since sp³ has no d orbitals) 6. **Conclusion**: The only compound with a hybrid orbital that has 20% d character is **SF4**. ### Summary of Findings: - CCl4: 0% d character - SF6: 33.33% d character - SF4: 20% d character (Correct Answer) - Cl2O: 0% d character

sp^(3) hybrid orbitals have equal s and p characters .

According to hybridisation theory, the % s-character in sp, sp^(2) and sp^(3) hybrid orbitals is 50, 33.3 and 25 respectively, but this is not true for all the species. When theta is the bond angle between equivalent hybrid orbitals then % s and p-character in hybrid orbitals (when only s and p-orbitals are involved in hybridisation) can be calculated by the following formula : costheta=(S)/(S-1)=(P-1)/(P) Q.
