Respuesta
The molecule with a trigonal planar shape is Boron trichloride (BCl3).
Explicación
## Step 1The shape of a molecule is determined by the arrangement of its electron pairs. The electron pairs in a molecule are arranged in a way that minimizes the repulsion between them. This is known as the VSEPR (Valence Shell Electron Pair Repulsion) theory.## Step 2Carbon monoxide (CO) has a linear shape. This is because it has only two atoms, and the electron pairs are arranged in a straight line.## Step 3Boron trichloride (BCl3) has a trigonal planar shape. This is because it has three atoms, and the electron pairs are arranged in a plane with 120-degree angles between them.## Step 4Silicon tetraiodide (SiI4) has a tetrahedral shape. This is because it has four atoms, and the electron pairs are arranged in a tetrahedron.## Step 5Carbon tetrafluoride (CF4) also has a tetrahedral shape. This is because it has four atoms, and the electron pairs are arranged in a tetrahedron.
