What is the shape of a molecule that has 4 atoms bonded to a central atom and no lone pairs of electrons?A.CubicB.OctahedralC.TetrahedralD.Trigonal-pyramidal

Break Down the Problem

1. Identify the number of atoms bonded to the central atom.
2. Determine the presence of lone pairs of electrons around the central atom.

Relevant Concepts

• According to VSEPR theory (Valence Shell Electron Pair Repulsion), the arrangement of atoms in a molecule can be predicted based on the number of bonded atoms and lone pairs.

Analysis and Detail

1. The problem states that there are 4 atoms bonded to a central atom.
2. It also states that there are no lone pairs of electrons.

Based on VSEPR theory:

• A molecule with four bonded atoms and no lone pairs adopts a tetrahedral geometry.

Verify and Summarize

• The tetrahedral shape occurs when there are four bonding pairs of electrons, and the geometry maximizes the distance between them, resulting in bond angles of approximately $109.5^\circ$.

Final Answer

C. Tetrahedral
