Examples are BF3, SO3 and COCL2.
SO3
SO3
Formaldehyde has a nonpolar trigonal planar molecule.
The molecular shape of SeO3 is trigonal planar. It has a central selenium atom bonded to three oxygen atoms, with no lone pairs on the central atom, resulting in a trigonal planar geometry.
The molecular geometry of BF3 is trigonal planar. It has three bond pairs and no lone pairs, resulting in a planar triangular shape. The bond angle between the three fluorine atoms is approximately 120 degrees.
For a truly trigonal planar molecule the bond angles are 120 0 exactly.
SO3
trigonal planar
CO32- is trigonal planar, bond angles are 1200
Formaldehyde has a nonpolar trigonal planar molecule.
Trigonal planar and tetrahedrral geometries tend to be present in polar molecules.
A trigonal planar molecule such as sulfur trioxide (SO3) or boron trihydride (BH3) has a trigonal planar shape. Trigonal pyramidal molecules such as ammonia (NH3) have bond angle closer to 107 degrees.
NF3 has a trigonal planar molecular shape due to its three bonding pairs and one lone pair of electrons around the central nitrogen atom. In contrast, PCl3 has a trigonal pyramidal molecular shape because it has three bonding pairs and one lone pair of electrons around the central phosphorus atom.
The molecular geometry of BF3 is trigonal planar. It has three bond pairs and no lone pairs, resulting in a planar triangular shape. The bond angle between the three fluorine atoms is approximately 120 degrees.
Not linear.
Some typical shapes include tetrahedral, linear (or straight), bent, trigonal planar, trigonal bipyramid, and ring compounds.
Trigonal Planar Electronic Geometry Geometry of Molecules: Trigonal Planar Three oxygen atoms are joined to the nitrogen atom in the NO3- ion to create a center atom. The configuration is trigonal planar, and the three oxygen atoms' bonds to the nitrogen atom have roughly 120-degree angles.
The molecular shape of SeO3 is trigonal planar. It has a central selenium atom bonded to three oxygen atoms, with no lone pairs on the central atom, resulting in a trigonal planar geometry.
