Anhydrous metal halides are commonly used starting materials for many organometallic compounds . (i.e., in reactions with Grignard reagents, the formation . of . metallocene, chromium(III) . Halogen is connected to a tetrahedral carbon. The carbon-halogen bond is polarized with the carbon having a partial positive charge and the halogen having a partial negative charge. The size of the halogen increases as you move down the group. 18. Amines and Amides. Lecture Presentation. Chapter 18 Amines and Amides.
