Carboxylic acids general formula

Acetic acid is miscible with water. Would you expect carboxylic acids, general formula CH3(CH2) COOH, to become more or less water soluble as n increases Explain.

A more eflicient and general synthetic procedure is the Masamune reaction of aldehydes with boron enolates of chiral a-silyloxy ketones. A double asymmetric induction generates two new chiral centres with enantioselectivities > 99%. It is again explained by a chair-like six-centre transition state. The repulsive interactions of the bulky cyclohexyl group with the vinylic hydrogen and the boron ligands dictate the approach of the enolate to the aldehyde (S. Masamune, 1981 A). The fi-hydroxy-x-methyl ketones obtained are pure threo products (threo = threose- or threonine-like Fischer formula also termed syn" = planar zig-zag chain with substituents on one side), and the reaction has successfully been applied to macrolide syntheses (S. Masamune, 1981 B). Optically pure threo (= syn") 8-hydroxy-a-methyl carboxylic acids are obtained by desilylation and periodate oxidation (S. Masamune, 1981 A). Chiral 0-((S)-trans-2,5-dimethyl-l-borolanyl) ketene thioketals giving pure erythro (= anti ) diastereomers have also been developed by S. Masamune (1986). 

Ether carboxylates are known for a long time. In 1934 a patent was applied for [1] in which some sodium salts of polyether carboxylated acids of the general formula... 

A dissertation from 1943 [2] describes an interesting investigation concerning synthesis and properties of pure ether carboxylates. With metallic sodium and chloroacetic acid ethyl ester followed by saponification, ether carboxylates were made with the general formula... 

Gerhardt et al. [34] described three possible ways to prepare alkylphenol-polyglycol ether carboxylates, namely, the method with NaOH and SMCA, the method by oxidation by means of oxygen, and the method whereby the nonionic reacts with acrylonitrile followed by hydrolyses with hydrochloric acid. The synthesis with acrylonitrile forms in contrast to the other two methods, carboxyethylated compounds with the general formula... 

Strzelbicki et al. synthesized n-alkyltri(oxyethylene)carboxylic acids with the general formula (0CH2CH2)30CH2C00H with n = 6, 8, 10, and 12... 

Write the general formula of each of the following types of compounds, using R to denote an organic group (a) amine (b) alcohol (c) carboxylic acid (d) aldehyde. 

Salicylic acid (Fig. 13.4.2) is an example of a carboxylic acid with the general formula R-COOH. In this class of organic compounds the carbonyl functionality... 

If a solute of the general formula AX (A is the chiral ion and X is an achiral ion) dissociates completely into ions once dissolved, then the solubility of the racemic conglomerate, SR, is equal to n%V2-SA (where SA is concentration of A in a solution saturated with AX ). If the solute is of the type AX, then 5 = V2-5a. The subscript n refers to the achiral ion and may be fractional, and so A2X must be represented by AXi/. If dissociation of AX is incomplete, SA lies between n i/2-SA and 2SA. For weakly dissociated electrolytes (such as carboxylic acids), SR is approximately 2SA. 

A], Alkoxide/oxide compounds of the speculated general formula BiO(OOCR) are formed by dissolving Bi203 in the carboxylic acid, followed by dilution and distillation of the excess acid (59). The compounds were characterized by elemental analysis and preliminary X-ray diffraction data.

This —COOH group is called the carboxyl group. The general formula for a carboxylic acid is R—COOH. Figure 1.23 shows some common carboxylic acids. 

The general formula for an ester is RCOOR, where R is a hydrogen atom or a hydrocarbon, and R is a hydrocarbon. You can think of an ester as the product of a reaction between a carboxylic acid and an alcohol, as shown in Figure 1.26. 

The general formula for a carboxylic acid is RCOOH, where R may be hydrogen or any alkyl or aryl group. The derivatives Vciry slightly from that formula ... 

Molecules may contain more than one carboxylic acid group. The dicarboxylic acids,which contain two carboxylic acid groups, are very important in areas such as organic synthesis. Many dicarboxylic acids have the general formula H00C-(CH2) -C00H. Table 12-1 lists how the names of the dicarboxylic acids relate to the value of n.
