Compare and contrast the intermolecular forces in alcohols and ethers. What type of intermolecular force is present in alcohols that are not present in ethers? The melting point of methane is low, so why is that in terms of intermolecular forces?
Inert organic solvents suitable for this purpose are, in particular, alcohols, such as ethanol, isopropanol, polar fatty acid amides, for example dimethylformamide, dimethylsulfoxide and more particularly methanol or tetrahydrofuran. The starting materials of the formulae II and IIB are known or are...
Why do alcohols have higher boiling points than ethers? Explain why benzophenone is soluble in methyl alcohol. Which are examples of salts: a. KCl b. HF c. NaBr d. CaO e. LiF Why is O_2 nonpolar? Why are alcohols soluble in water sometimes, but not as the carbon chain grows longer?
These pyridyloxy-phenoxy-alkanecarboxylic acid derivatives of the formula I are stable compounds which are soluble in customary organic solvents, such as alcohols, ethers, ketones, dimethylformamide, dimethylsulphoxide, etc. EXAMPLE 1 Methyl α-[4-(3'-chloro-5'-cyano-6'-methyl-pyrid-2'-yl)...
True or False: Ethers have stronger intermolecular forces than alkanes but weaker intermolecular forces than alcohols. The strength of dispersion forces depends on the molar mass but the shape of the molecules has no effect on dispersion forces. True or false? True or false? T...
e., about .1%-5% of various carboxylic acids, such as fatty or naphthenic acids, may be present, and in many instances this may even be beneficial. Both polar and non-polar vehicles may be employed. Among the former are water, alcohols, such as methyl, ethyl, propyl, isopropyl, butyl...
The Kovats indices of 3- and 4-substituted methoxy-biphenyls, methoxy-benzenes, and alkyl phenyl ethers on non-polar column Ultra 1 (see Table S4) were taken from the literature [14]. The collected Δgl𝐻omΔlgHmo(298.15 K) values in Table S4 show a very good linear correlation with...
