Electron poor which is usually shown by charge open octet. of Acids and Bases. Acids are substances which produce hydrogen ions H. +. , in solution.. Bases are substances which produce hydroxide ions OH- in solution.. Neutralization . happens because hydrogen ions and hydroxide ions react to produce water.. Several forms of hydride (H-) find use in organic chemistry, including . NaH. , CaH. 2. , LiAlH. 4. , NaBH. 4. , and NaBH. 3. CN (and several others).. The reactivity of hydride varies considerably, depending on the nature of the element to which it is attached. It can function as either a base . Structures and Properties. 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. Amine nomenclature. diisopropylamine. pyrrole. nicotine. histamine. pyrrolidine. Formation of amines. triethylamine. Mechanism for LAH reduction of amides. 1-methylpiperidine. One equivalent . SN2 is faster the more R groups on N. HNO. 2. HNO. 3. Which is the stronger base?. N. O. 2. -. N. O. 3. -. Acid-Base Reactions. strong acid + strong base. strong acid + weak base. weak acid + strong base. weak acid + weak base. Extent of Weak Acid-Weak Base Reactions. . Ethers are relatively unreactive.. Ethers are often used as solvents in organic reactions.. Ethers oxidize in air to form explosive hydroperoxides and peroxides.. “Crown” ethers are useful as enhancers in nucleophilic substitution and other reactions. ALkanes. Chapter 10.2:. Structure, bonding and chemical reactions involving functional group inter-conversions are key strands in organic chemistry. Chapter 20.1:. Key organic reaction types include nucleophilic substitution, electrophilic addition, electrophilic substitution, and redox reactions. Reaction mechanisms vary and help in understanding the different types of reactions taking place.. Web Based with Links to Tools . Blueprint for a Stronger Club .
