Answer:
Tetrahedral
Explanation:
Because there is one central atom (C) and 4 surrounding atoms, you can assume that the molecular shape is tetrahedral. However, it is important to add the valence electrons and assign them to each of the atoms to make sure there are no double/triple bonds or lone pairs. This could change the shape.
C = 4 v.e.
F = 7 v.e.
Cl = 7 v.e.
4 + 2(7) + 2(7) = 32 total valence electrons
There are 6 lone pairs around each outer atom and two electrons in each bond.
(6 electrons x 4 outer atoms) + (2 electrons x 4 bonds between atoms) = 32 electrons
This adds up to the total valence electrons. Carbon wants 8 valence electrons. This is satisfied by the 4 bonds between it and the outer atoms. The outer atoms want 8 valence electrons as well. This is satisfied by the 6 electrons (in the form of lone pairs) and 1 bond between them and carbon.
