nh3
The molecular geometry of the BR3 Lewis structure is trigonal planar.
The molecular structure of BF3 is trigonal planar, consisting of one boron atom bonded to three fluorine atoms. The boron atom is in the center with each fluorine atom positioned at the corners of an equilateral triangle.
Not linear.
CO32- is trigonal planar, bond angles are 1200
nh3
Sulfur tetraoxide is a trigonal planar. There is the sulfur in the middle and three oxygen that surrounds it with all of them a double bond linking them to the sulfur.
Trigonal pyramid will be its molecular shape. It will have tetrahedral electron domain geometry.
It is a trigonal planar structure - the nitrogen atom in the center.
For a truly trigonal planar molecule the bond angles are 120 0 exactly.
Trigonal planar
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.
The molecule H2CO, formaldehyde, has a trigonal planar molecular shape with a bond angle of 120 degrees. It is a polar molecule due to the difference in electronegativity between carbon and oxygen, resulting in a net dipole moment.
