Sp3-Hybridization MDCAT Quiz; geometry of molecules when the central atom forms four bonds to other atoms. Understanding sp³ hybridization gives one the capability to answer questions in the MDCAT Quiz pertaining to molecular structures, bonding, and the shape of molecules.
H2: Concept of sp³ Hybridization
One s orbital and three p orbitals of the same atom combine to make four equivalent hybrid orbitals known as sp³ hybrid orbitals. These sp³ hybrid orbitals orient themselves in a tetrahedral geometry for minimum electron-electron repulsions with bond angles of approximately 109.5°. These are formed by atoms with four valence electrons, such as carbon in methane (CH₄). For CH₄, the carbon is sp³ hybridized, giving four equivalent sp³ hybrid orbitals, which overlap with 1s orbitals of H atoms to produce four sigma bonds. The CH₄ molecule is in a tetrahedron, with a 109.5° bond angle.
H3: MCQs on sp³ Hybridization
The MDCAT Quiz on sp³ hybridization is designed to test the student’s knowledge in identifying molecules that undergo sp³ hybridization and understanding the geometry of their molecular structure. Students will be expected to predict the shape and bond angles of molecules such as methane (CH₄), ethane (C₂H₆), and ammonia (NH₃), where the central atom undergoes sp³ hybridization. It will also assess the understanding of how the arrangement of hybrid orbitals leads to the stability and properties of these molecules. Practicing these quiz questions will help students strengthen their understanding of sp³ hybridization and prepare for related questions in the MDCAT exam.
H2: Examples of sp³ Hybridized Molecules
There are a variety of molecules that have sp³ hybridization, and knowing their structure is an essential part of MDCAT preparation. Here are some key examples:
Methane (CH₄): The carbon atom at the center undergoes sp³ hybridization, making four sigma bonds with hydrogen atoms. The molecule has a tetrahedral shape, with bond angles of 109.5°.
Ethane (C₂H₆): Each carbon atom in ethane undergoes sp³ hybridization, forming single bonds with hydrogen atoms and with the other carbon atom. This results in a tetrahedral geometry for each carbon atom.
Water (H₂O): Although water has two lone pairs on oxygen, oxygen in H₂O undergoes sp³ hybridization, forming two sigma bonds with hydrogen atoms. The molecule has a bent shape, with bond angles of approximately 104.5° due to the presence of lone pairs.
