Preparation and Reactions of carboxylic acid derivatives
Question#1
A carboxylic acid is converted into its anhydride using [J & K 2005]
P2O5 acts as a dehydrating agent.
Question#2
Order of hydrolysis for the following [DPMT 2005]
(I) RCOCl
(II) RCOOR
(III) RCONH 2
(IV) (RCO)2 O
(a) oF all the acid derivatives, acid chlorides, i.e. CH3CO-Cl is most reactive.
The order of reactivity of acid derivatives decreases in the following order, RCOCl > (RCO)2O > RCOOR > RCONH2.
Question#3
Urea upon hydrolysis yields [Pb. CET 2001]
\( O=C<_{NH_2}^{NH_2} \xrightarrow{HOH} O=C<_{OH}^{OH} + NH_3 (\uparrow)\)
Question#4
The reaction of an ester RCOOR' with an alcohol R"OH in the presence of an acid gives [Kerala PMT 2004]
(d) \( R-COOR' + R"OH \xrightarrow{H+} RCOOR" + R'OH \) The exchange of alcohol residue known as alcoholysis or trans esterification
Question#5
Acetamide is [MP PET 1990; RPMT 1999]
