WebSep 2, 2024 · The 6 basic molecular shapes are linear, trigonal planar, angular (bent), tetrahedral, trigonal pyramidal, and trigonal bipyramidal. ... Water has 4 regions of electron density around the central oxygen atom (2 bonds and 2 lone pairs). These are arranged in a tetrahedral shape. The resulting molecular shape is bent with an H-O-H angle of 104.5°. WebIn conclusion, organic chemistry relies heavily on oxidation and reduction reactions to change molecules into various shapes. Reduction reactions entail taking oxygen away from a molecule, whereas oxidation reactions involve adding oxygen to a molecule. Aldehydes and alcohols can be converted into one another using reagents like KMnO4-NaOH and ... WebShapes of Molecules. Water and carbon dioxide are both triatomic molecules. The similarities go even further - they are both partially formed from oxygen and they both contain covalent bonds. However, their molecules are very different in shape. Whilst the atoms in carbon dioxide are held in a straight line, water is a bent molecule. scooters manchester
