The molecular geometry, or three-dimensional shape of a molecule or polyatomic ion, can be determined using valence-shell electron-pair repulsion (abbreviated VSEPR and pronounced “VES-per”) theory, in which the basic principle is valence electrons around a central atom stay as far apart as possible to. minimize the repulsions.

4 ημέρες πριν · We will now look into the VSEPR chart to find out the shape: As we can find out, the 3D geometry of COCl2 is trigonal planar. The bond angle of C-Cl bonds is around 111.8 degrees ( less than 120 degrees due to C=O electron density that reduces the bond angle). COCl2 Hybridization
Q: Are these bond angles exact for each molecule? A: No, the bond angles are slightly influenced by whether the substituent is an atom or a lone pair and by atomic radii. Hence, the bond angles shown are close estimations, and not exact. A good example of this is methane and ammonia, as shown below.
Chemical Bonding and Molecular Geometry. Figure 7.1 Nicknamed “buckyballs,” buckminsterfullerene molecules (C60) contain only carbon atoms. Here they are shown in a ball-and-stick model (left). These molecules have single and double carbon-carbon bonds arranged to form a geometric framework of hexagons and pentagons, similar to the pattern ...
