Explain Why H2o and Co2 Molecules Have Different Shapes
This theory states that as electrons are negatively charged the valence electrons in different atoms in a molecule repel each other. For example molecules CO_2 and H_2O both have three atoms. Why Is Co2 Linear But H2o Is Angular Quora However water has a bent structure because only the oxygen atom possesses a lone pair which brings the bonding electron pairs closer. . The shape means most of the negative charge from the oxygen on side of the molecule and the positive charge of the hydrogen atoms is on the other side of the molecule. VSEPR theory uses lone pairs. The lone pairs push the. This causes the water molecule to have a non-linear shape. The molecular geometry of NH 3 is called trigonal pyramidal see Figure 9. Although both CO2 and H2O are triatomic molecules the shape of H2O molecule is bent while that of CO2 is linear. Although both CO2 and H2O are triatomic molecules the shape of H2O molecule is ...
