Question#2
. Acetic acid reacts with PCl5 to form [Pb. CET 2001]
\( CH_3COOH + PCl_5 \rightarrow CH_3COCl + HCl + POCl_3 \)
Question#3
The -OH group of an alcohol or the -COOH group of a carboxylic acid can be replaced by -Cl using [CBSE PMT 2004]
\( R-OH + PCl_5 \rightarrow R-Cl + POCl_3 + HCl \)
\( RCOOH + PCl_5 \rightarrow RCO-Cl + POCl_3 + HCl \)
Question#4
The reagent which does not give acid chloride on treating with a carboxylic acid is [KCET 2004]
\( CH_3COOH + Cl_2 \rightarrow CH_2Cl-COOH + HCl \)
\( CH_3COOH + PCl_3 \rightarrow CH_3COCl + POCl_3 + HCl \)
\( CH_3COOH + SOCl_2 \rightarrow CH_3COCl + SO_2 + HCl \)
\( CH_3COOH + PCl3 \rightarrow 3CH3COCl + H3PO3 \)
Question#5
