Increase, resonance 2. lic esters are called e cyclic amides are called A. Epoxides, alkanes B. Lactams, lactones C. Lactams, alkenes D. Lactones, lactams 3. An acid catalyzed esterification (a reaction between a carboxylic acid and an alcoho) is called A Williamson synthesis B. Diels-Alders C. Fischer esterification D. Tautomerization 4 The linkages that join amino acids together to form proteins are primarily bonds A, amides B. amines C. hydrogen D. double

Explanation / Answer

1.

Correct answer is B

The acidic strength of carboxylic acid depends upon the ease with which it ionizes to give hydrogen ion.

RCOOHRCOO- + H+

The ease with which hydrogen ion is released depends upon the stability of the corboxylate ion.The electron withdrawing group attracts electron (negative inductive effect) ,as a result, stability of carboxylate ion increases and acidity of the molecule increases.
