Which of the following functional groups is absent in the structure below? a) Nitrile b) Ether c) Alcohol d) Alkene e) Ester What type of organic compound contains the following functional group? What is an example of an oxygen-containing functional group?
Mixed ethers are those with different R groups—for example, C5H11OCH2C6H5 (amyl benzyl ether). Some ethers have trivial names, such as anisole (CH3OC6H5, the methyl ether of phenol) and cellosolves (the monoethers of ethylene glycol). As a rule, ethers are poorly soluble in water ...
For example, experimental studies on the (111) and (100) surfaces indicate the presence of carbonyl and ether groups43,44,45,46 after the removal of loosely-bound compounds and organic contaminants. The few experimental studies that exist for the (110) surface are also interpreted in the ...
The unique properties of ethers (i.e., that they are strongly polar, with nonbonding electron pairs but no hydroxyl group) enhance the formation and use of many reagents. For example, Grignard reagents cannot form unless an ether is present to share its lone pair of electrons with the magne...
For example, sulfonation alters the nature of chain packing, thus drastically reduces the crystallizability of PEEKs. However, Tg increases with sulfonation due to increased intermolecular interactions. With a DS of 0.72 (the concentration of –SO3H group per repeat unit of PEEK), a fully ...
A perfluoro(poly)ether group-containing silane compound which contains a structure represented by -PFPE-X-SiRakRblRcm. For example, PFPE represents a perfluoro(poly)ether group; X represents a substituted or unsubstituted alkylene group having 2-20 carbon atoms; Ra represents a functional group ...
Draw an example of an organic molecule with an aldehyde functional group. a) Draw all resonance forms of the following compound. b) Write the IUPAC name for the following compound. Draw the Lewis structure for this molecule, and include all lone pairs and abbreviated ...
There are always two side chains in ethers R−O−R, the longest of these two side chains is the parent chain. Use the alkane base name to write the name of the parent chain. Example: for a two-carbon parent chain, ethane, a three-carbon parent chain, propane....
The group is stable in the pH 2–14 range and it is generally impervious to nucleophiles, organometallics, hydrogenation (except in acetic acid), hydride, and oxidizing agents. It is usually removed with fluoride (TBAF or aq HF). In an example taken from the Cook and coworker’s63 ...
The formation of ethyl acetate from acetic acid and ethanol is an example of esterification. 12 Ether An organic compound with an oxygen atom connected to two alkyl or aryl groups. Diethyl ether is a common laboratory solvent. 11 Ester A chemical compound derived from an acid where an -OH ...
