Three Ways to Describe Crystal Structures Three Structural sketches of P4O10 molecules: (a)Stick-ball model:showing that the P-O chemical bond is the tetrahedral coordination and sp3 covalent bonds
Classes of Halides Alkyl: Halogen, X, is directly bonded to sp3 carbon. Vinyl: X is bonded to sp2 carbon of alkene. Aryl: is bonded to sp2 carbon on benzene ring. Examples:
