He also has published research on inorganic chemistry and electrochemistry. The most reactive site in an alcohol molecule is the hydroxyl group, despite the fact that the O–H bond strength is significantly greater than that of the C–C, C–H and C–O bonds, demonstrating again the difference between thermodynamic and chemical stability. Professor Kotz has co-authored three textbooks in several editions - INORGANIC CHEMISTRY, CHEMISTRY & CHEMICAL REACTIVITY, and THE CHEMICAL WORLD - along with the INTERACTIVE GENERAL CHEMISTRY CD-ROM.
Indeed, the dipolar nature of the O–H bond is such that alcohols are much stronger acids than alkanes (by roughly 10 30 times), and nearly that much stronger than ethers. Consequently, the covalent bonds of this functional group are polarized so that oxygen is electron rich and both carbon and hydrogen are electrophilic, as shown in the figure below.
The electronegativity of oxygen is substantially greater than that of carbon and hydrogen. Number Textbook: Chemistry and Chemical Reactivity (4th Edition) by Kotz and. Unlike the alkyl halides, this group has two reactive covalent bonds, the C–O bond and the O–H bond. Ap Chemistry Unit 4 Practice TestAP Chemistry Practice Test: Chapter 4. Recognized as one of the most progressive and engaging General Chemistry texts in the market, Kotz, Treichel, Townsend and Treichel help students develop a deeper understanding of general chemistry concepts.The text emphasizes the visual nature of chemistry, illustrating the close interrelationship of the macroscopic, symbolic, and particulate. The functional group of an alcohol is the hydroxyl group, –OH. Alcohols contain the hydroxy functional group (-OH), bonded to a carbon atom of an alkyl or substituted alkyl group. They can be prepared from and converted into many different types of compounds. \)Īlcohols are some of the most important molecules in organic chemistry.
