Unformatted text preview: Version 013 – Quiz 3 – Laude – (53755) 1 This print-out should have 8 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 5.0 points Which of the following statements concerning hybrid orbitals is/are true? I) Hybrid orbitals are energetically degen- erate. II) Any element can form sp 3 d 2 hybrid or- bitals. III) Hybridizing a 2 s and a 2 p orbital would produce one sp hybrid orbital. 1. II, III 2. II only 3. III only 4. I, II 5. I, II, III 6. I, III 7. I only correct Explanation: Statement I is true; hybridization was de- veloped as a theoretical framework to ex- plain the energetic degeneracy of bonds in molecules. Statement II is false; hybridiza- tion involving d orbitals requires access to empty d orbitals, and thus begins in period 3. Statement III is false; the number of or- bitals used to hybridize is always equal to the number of hybridized orbitals, so using a 2 s and a 2 p orbital would result in two sp...
