Classify the reagents shown in bold in the following equations as nucleophiles or electrophiles : (a) CH_3 COOH + HO^(-) to CH_3 COO^(-) + H_(2) O (b) CH_3 CH_2 Br + HS^(-) to CH_3 CH_2 SH+ Br^(-) (c ) C_6 H_6 + CH_3 CO^(+) to C_6 H_5 COCH_(3) (d) CH_3 COCH_(3) + CN^(-) to CH_3 underset(underset(CN)|)overset(overset(OH)|)C - CH_(3)

6 gm of CH_(3)COOH, 6 gm of NaOH and 6.3 gm of HNO_(3) are dissolved in 1L of water. If K_(a) of CH_(3)COOH is 10^(-5) then calculate pH of resulting solution.

How many of the following compounds would give Iodoform test (1) s CH_(3) - CO - CH_(2) - CO - OCH_(3) (2) C_(6) H_(5) - CO - CH_(2) - CO - C_(6)H_(5) (3) CH_(3) - CHCl - CH_(2) - CH_(3) (4) CH_(3) - CHNH_(2) - CH_(3) (5) CH_(3) - CO - CH_(2)I (6) CH_(3) - CO - O - CO - CH_(3) (7) CH_(3) - CO - O - CH_(3) (8) CH_(3) - CO - Cl (9) CH_(3) - CHOH - CH_(2) - CH_(3) (10) CH_(3) - CO - CH_(2) - CHOH - CH_(3)
