CH4 has this geometry:
- A) trigonal
- B) planar
- C) tetrahedral
- D) octahedral
Correct Answer: C) tetrahedral
Explanation
CH\(_4\), also known as methane, is a molecule that consists of one carbon atom (C) bonded to four hydrogen atoms (H). The geometry of a molecule is determined by the arrangement of its atoms in three-dimensional space.
In the case of CH\(_4\), the carbon atom is at the center, and the four hydrogen atoms are arranged around it. The carbon atom forms single covalent bonds with each of the hydrogen atoms, sharing a pair of electrons to complete its valence shell with eight electrons.
The geometry of CH\(_4\) istetrahedral. In a tetrahedral arrangement, the four hydrogen atoms are positioned at the corners of a tetrahedron, a pyramid shape with four triangular faces, with the carbon atom at the center. This arrangement minimizes the repulsion between the electron pairs in the molecule, resulting in a stable structure.
Other geometries mentioned in the options, such as trigonal (three-sided), planar (flat), octahedral (eight-sided), and linear, do not apply to CH\(_4\). These geometries are associated with other types of molecules, depending on the number of atoms involved and their electronic configurations.
