Unformatted text preview: A base is an electron-pair donor. Any electron deficient centre will be able to act as a Lewis acid (eg carbocations). The dissociation constant Ka for any weak acid in water is: Large Ka = strong acid (highly dissociated) pKa = -ive log Ka small pKa = strong acid Strong acid = weak conjugate base Strong base = weak conjugate acid and vice versa PART II – REACTIONS OF ALKANES, ALKENSE AND ALKYNES double dehydrohalogenation Base 1 R R4 R R 3 R 2 R 3 PART III – CARBONYL CHEMISTRY CARBONYL CHEMISTRY preparation addition reaction CARBOXYLIC ACIDS Properties and preparation of carboxylic acids Reactions of carboxylic acids LiAlH4 R OH alcohols O CrO3 H+/heat O CrO3 C N R O R'OH H+ R R H aldyhydes R O anhydrides carboxylic acids R'NH2 H+ H2O + H2O R' N H amides + H2O O esters O R R nitriles + R' OH R H+/ H2O O O SOCl2 ALKANES synthesis and reactions ALKENES synthesis and reactions O O Nucleophilic acyl substitutions Nu R Cl R Nu acid chlorides We’ve helped over 50,000 students get better grades since 1999!
