what is the molecular geometry of trans-difluroethylene: trans-C2H2F2?
i want to say it is a tetrahedral because it has four atoms and no lone pairs, but im not sure.
the bond angles of this is 109.5 and that is is the bond angles for tetrahedrals so is it good to conclude that this structure is a tetrahedral
Answered elsewhere.
To determine the molecular geometry of trans-difluoroethylene (trans-C2H2F2), we need to consider its Lewis structure and the arrangement of its atoms.
The Lewis structure for trans-difluoroethylene is:
C (double bond to) C
\ /
F - F
From this structure, we can see that there are four atoms and no lone pairs around the central carbon atom. The central carbon is bonded to two hydrogen atoms and two fluorine atoms.
Based on this information, you are correct in stating that the molecule has a tetrahedral geometry. In a tetrahedral molecule, all four electron groups (atoms or lone pairs) are arranged around the central atom in a symmetrical manner. The bond angles in a tetrahedral structure are approximately 109.5 degrees. In the case of trans-difluoroethylene, the two hydrogen atoms and two fluorine atoms are arranged at the corners of a tetrahedron.
Therefore, you can conclude that the molecular geometry of trans-difluoroethylene is tetrahedral, with bond angles of approximately 109.5 degrees.
To determine the molecular geometry of trans-difluoroethylene (trans-C2H2F2), we need to first draw its Lewis structure:
C = central atom
F = fluorine atom

From the Lewis structure, we can see that trans-difluoroethylene consists of two carbon atoms connected by a double bond and each carbon atom is bonded to a fluorine atom. Therefore, the molecular formula is C2H2F2.
Now, let's determine the molecular geometry.
The VSEPR (Valence Shell Electron Pair Repulsion) theory states that electron pairs will repel each other, causing the molecule to adopt a particular shape to minimize this repulsion.
In the case of trans-difluoroethylene, there are no lone pairs of electrons around the central carbon atoms. Each carbon atom is bonded to two other atoms (one fluorine and one carbon atom).
This arrangement of two bonding pairs and no lone pairs around each carbon atom corresponds to the molecular geometry known as linear. Therefore, the molecular geometry of trans-difluoroethylene is linear.
It's important to note that while the bond angles of a tetrahedral molecule are approximately 109.5 degrees, this does not imply that every molecule with bond angles of 109.5 degrees is a tetrahedral. In the case of trans-difluoroethylene, the bond angles do not follow the tetrahedral pattern, as the molecule is linear.
