A) \[NaHC{{O}_{3}}\]test
B) lodoform test
C) \[FeC{{l}_{3}}\]test
D) Both [a] and [b]
Correct Answer: D
Solution :
(i)\[\underset{Benzoic\text{ }acid}{\mathop{{{C}_{6}}{{H}_{5}}COOH}}\,+NaHC{{O}_{3}}\xrightarrow[{}]{{}}{{C}_{6}}{{H}_{5}}COONa\] \[+C{{O}_{2}}+{{H}_{2}}O\] \[{{C}_{6}}{{H}_{5}}COO{{C}_{2}}{{H}_{5}}\xrightarrow[{}]{NaHC{{O}_{3}}solution}\]no reaction (ii)\[{{C}_{6}}{{H}_{5}}COOH+NaOH+{{I}_{2}}\xrightarrow[{}]{{}}\]no reaction \[{{C}_{6}}{{H}_{5}}COO{{C}_{2}}{{H}_{5}}+NaOH\xrightarrow[{}]{Boil}\underset{sod.\text{ }benzoale}{\mathop{{{C}_{6}}{{H}_{5}}COONa}}\,\] \[\underset{ethanol}{\mathop{+C{{H}_{3}}C{{H}_{2}}H}}\,\] \[C{{H}_{3}}C{{H}_{2}}OH+4{{I}_{2}}+6NaOH\xrightarrow[{}]{\Delta }HCOONa\] \[+\underset{iodoform}{\mathop{CH{{I}_{3}}}}\,+\underset{(vellow\,ppt.)}{\mathop{5NaI+5{{H}_{2}}O}}\,\]
