1. Calculate the total number of electrons in the valence shell of all the atoms in the molecule.
Wrong. Check the valence electrons of C, O and Cl.
|
|
Correct.
24 electrons
|
|
No es correcto. Check the valence electrons of C, O and Cl.
|
2. Select the central atom in the molecule.
Wrong. The central atom is always the less electronegative in the molecule.
|
|
Correct. Carbon is less electronegative than O or Cl.
C
|
3. How many electrons are needed to form single bonds between C and the other three atoms in the molecule?
Wrong. More electrons are needed.
|
|
Correct. Each atom shares two electrons with carbon.
A total of
6 electrones.are needed.
|
|
Wrong. three single bonds require less than 8 electrons.
|
4. How many electrons are needed to complete the octeto in all the terminal atoms?
Correct. Each terminal atom shares two electron with carbon.
Will need 6 electrons more to complete the octeto. That makes a total of
18 electrons.
|
|
Wrong. Each terminal atom shares two electron with carbon.
With seven electrons more each atom will overpass the octeto. Oxigen cannot expand the octeto.
|
|
Wrong. Each terminal atom shares two electron with carbon.
With eight electrons more each atom will overpass the octeto. Oxigen cannot expand the octeto.
|
5. All the 24 electrons have been temporarily located but carbon has not completed the octeto. How do we have to reorganize the electrons?
C remains with six electrons. | Wrong. Carbon generally complets the octeto
|
Cl transfers two electrons to C. | Wrong That involves a double bond between Cl and C. Such bond is not
favorable between these two atoms,

|
Oxygen transfers two electrons to carbon | Correct Such transfer produces a
C=O double bond in the molecule.

6. How is the geometry of this molecule?Structures
Wrong Check the structures table..
|
|
Correct. Three bonds around the carbon atom correspond to an environment of type AX3.
Triangular planar structure..
|
|
Wrong. Check the structures table.
