Additional Physical Format: Online version: Clapp, Leallyn B. (Leallyn Burr), Chemistry of the OH group. Englewood Cliffs, N.J., Prentice-Hall . Table of Contents Functional groups in organic chemistry Functional groups in organic chemistry Functional groups are structural features distinguish one organic molecule from another. They determine a molecule’s geometry, physical properties, and reactivity. Actually, a functional group is an atom or a group of atoms with characteristic chemical and physical properties. It is the reactive [ ]. This is very confusing! Different sources quote totally different chemical shifts for the hydrogen atom in the -OH group in alcohols - often inconsistently. For example: The Nuffield Data Book quotes - , but the Nuffield text book shows a peak at about The . A group with a carbon-nitrogen double bond is called an imine, or sometimes a Schiff base (in this book we will use the term 'imine'). The chemistry of aldehydes, ketones, and imines will be covered in .

Even though you would be tempted to label the OH on the carbonyl group as an alcohol, the presence of the C=O completely changes the chemical properties of the OH and it does not have the properties of an alcohol group and is not labeled as such. A protective group (also referred to as "protecting group") is a reversably formed derivative of an existing functional group in a molecule. The protective group is temporarily attached to decrease reactivity so that the protected functional group does not react under synthetic conditions to which the molecule is subjected in one or more. COVID Resources. Reliable information about the coronavirus (COVID) is available from the World Health Organization (current situation, international travel).Numerous and frequently-updated resource results are available from this ’s WebJunction has pulled together information and resources to assist library staff as they consider how to handle coronavirus.
Reaction of the hemiacetal OH group (anomeric OH group) of monosaccharide A with an OH group of monosaccharide B results in the formation of an acetal A–B and water. The formed glycoside is a disaccharide, and the acetal linkage between the two monosaccharide residues is . In organic chemistry, functional groups are specific substituents or moieties within molecules that are responsible for the characteristic chemical reactions of those molecules. The same functional group will undergo the same or similar chemical reaction(s) regardless of the size of the molecule it is a part of. This allows for systematic prediction of chemical reactions and behavior of. "The Chemistry Book" [ - - Science - Chemistry] "The Chemistry Book" is an excellent source for information about the science of chemistry. The format of the book is quite intriguing. There are one page essays accompanied by a full page related drawing or photograph. The pages follow a chronological history of concepts /5(40). This book considers the raw materials used to build the polyurethane polymeric architecture. It covers the chemistry and technology of oligo-polyol fabrication, the characteristics of the various oligo-polyol families and the effects of the oligo-polyol structure on the properties of the resulting polyurethane/5(2).
