Answer true or false.
(a) The two most important reactions of alcohols are their acid-catalyzed dehydration to give alkenes and their oxidation to aldehydes, ketones, and carboxylic acids.
(b) The acidity of alcohols is comparable to that of water.
(c) Water-insoluble alcohols and water-insoluble phenols react with strong bases to give watersoluble salts.
(d) Acid-catalyzed dehydration of cyclohexanol gives cyclohexane.
(e) When the acid-catalyzed dehydration of an alkene can yield isomeric alkenes, the alkene with the greater number of hydrogens on the carbons of the double bond generally predominates.
(f) The acid-catalyzed dehydration of 2-butanol gives predominantly 1-butene.
(g) The oxidation of a primary alcohol gives either an aldehyde or a carboxylic acid depending on experimental conditions.
(h) The oxidation of a secondary alcohol gives a carboxylic acid.
(i) Acetic acid, CH3COOH, can be prepared from ethylene, CH2=CH2, by treatment of ethylene with H2O/H2SO4, followed by treatment with K2Cr2O7/H2SO4.
(j) Treatment of propene, CH3CHwCH2, with H2O/ H2SO4 followed by treatment with K2Cr2O7/H2SO4 gives propanoic acid, CH3CH2COOH.
