15 Questions
How many atomic electron orbitals combine to create the sp3 hybrid orbital?
Four
What percentage of the sp3 hybrid orbital is composed of s orbital energy?
25%
Why are there four sp3 orbitals formed instead of each orbital remaining individual?
To share the electron energy equally
What is the distinctive shape created when the s orbital energy combines with the p orbital energy in a hybrid?
Hot air balloon with a basket underneath
How does the distribution of s orbital energy affect the lobes of the resulting hybrid orbital?
It enlarges one lobe and reduces the other
Which type of bond is stronger and shorter than a sigma bond?
Pi bond
In the case of ethylene (H2C=CH2), how many pi bonds are formed?
1
What type of hybrid orbitals are formed in an sp3 hybridization?
One s orbital and three p orbitals
Which molecule exhibits sp2 hybridization?
Boron trifluoride
How many pi bonds are present in a triple bond like acetylene?
2
What is the shape of a hybrid orbital formed by combining s and d orbitals?
Bow-tie shape
In ethane (CH3 CH3), what is the hybridization of the carbon atoms?
sp3
What determines the hybridization of an atom in a molecule?
Number of electrons available to be shared
What happens to the hybridized orbitals when a carbon atom forms a double bond?
They become sp2 hybridized
What shape do sp3 hybrid orbitals form in a molecule?
Tetrahedral shape
This quiz covers the formation of hybrid orbitals from atomic electron orbitals by combining them to create mixed hybrid orbitals like sp3. The hybrid orbitals share electron energy equally, resulting in a different structure than individual orbitals.
