Hybridization and Bonding Concepts

How many electrons can an f-orbital accommodate at most?

• 2

• 6

• 10

• 14

What is achieved when different types of atomic orbitals combine to form new hybrid orbitals with equal energy levels?

• Orbital stability

• Orbital degeneracy

• Orbital expansion

• Orbital contraction

What type of hybridization occurs when one s-orbital and two p-orbitals combine?

• sp

• sp2

• sp3

• dsp2

What is the hybridization and molecular geometry of methane (CH4)?

• sp, linear

• sp2, trigonal planar

• sp3, tetrahedral

• dsp2, square planar

What is the approximate bond angle in a molecule with sp3 hybridization and a tetrahedral geometry?

• 90°

• 109.5°

• 120°

• 180°

What is the molecular geometry of an alkene with SP2 hybridization?

• Linear

• Tetrahedral

• Trigonal planar

• Bent

How many sigma (σ) and pi (π) bonds are present in a carbon-carbon double bond?

• One σ, one π

• Two σ, zero π

• Zero σ, two π

• Two σ, two π

Why is a sigma (σ) bond generally stronger than a pi (π) bond?

• Sigma bonds involve sideways overlap, while pi bonds involve axial overlap

• The extent of overlapping is greater in sigma bonds

• Pi bonds are formed by s-orbital overlap

• Sigma bonds are always formed between two p-orbitals

What is the hybridization state and molecular geometry of carbon atoms involved in a carbon-carbon triple bond?

• SP2, Trigonal planar

• SP, Linear

• SP3, Tetrahedral

• SP2, Bent

What are the hybridization states of the carbon atoms in the compound CH2=C=O, from left to right?

• SP2, SP, SP2

• SP3, SP2, SP

• SP, SP2, SP

• SP2, SP2, SP2
