Isomer C gives a carboxylic acid (ethanoic acid). Osmium tetroxide (OsO 4) is a widely used oxidizing agent for such purpose.Potassium permanganate can be used as well, though further oxidation is prone to occur to cleave the diol because it is a stronger oxidizing agent (10.7.2). As for example the oxidation number of chromium in CrCl3 is +3. Partial reduction of carboxylic acids directly to aldehydes is not possible, but such conversions have been achieved in two steps by way of certain carboxyl derivatives.

Students should be able to: describe what happens when any of the first four carboxylic acids react with carbonates, dissolve in water, react with alcohols. Sodium borohydride, NaBH 4, does not reduce carboxylic acids; however, hydrogen gas is liberated and salts of the acid are formed. Because of its position midway in the second horizontal row of the periodic table, carbon is neither an electropositive nor an electronegative element; it therefore is more likely to share electrons than to gain or lose them. Conformations and Stereochemistry. Also called -olefins, terminal alkenes are more useful. Number the carbon chain, beginning at the end nearest to the carboxylic acid group. Since approximate ranges of p K a values are listed in the table, the exact p K a value of a group varies for different compounds because of the structural differences.
