Question : 8 of 36
Marks: +1, -0
Complete the following chemical equations:
(i) CH3COOC2H5+NaOHightarrow\mathrm{CH}_3\mathrm{COOC}_2\mathrm{H}_5 + \mathrm{NaOH} ightarrow
(ii) CH3COOH+NaOHightarrow\mathrm{CH}_3\mathrm{COOH} + \mathrm{NaOH} ightarrow
(iii) C2H5OH+CH3COOH→extConc.H3SO4\mathrm{C}_2\mathrm{H}_5\mathrm{OH} + \mathrm{CH}_3\mathrm{COOH} \xrightarrow{ ext{ Conc. } \mathrm{H}_3\mathrm{SO}_4}
Solution:  
(i) CH3COOC2H5+NaOH→H2OC2H5OH+CH3COONa\mathrm{CH}_3\mathrm{COOC}_2\mathrm{H}_5 + \mathrm{NaOH} \xrightarrow{\mathrm{H}_2\mathrm{O}} \mathrm{C}_2\mathrm{H}_5\mathrm{OH} + \mathrm{CH}_3\mathrm{COONa}
(ii) CH3COOH+NaOH→extHCH3COONa+H2O\mathrm{CH}_3\mathrm{COOH} + \mathrm{NaOH} \xrightarrow{ ext{ H }} \mathrm{CH}_3\mathrm{COONa} + \mathrm{H}_2\mathrm{O}
(iii) C2H5OH+CH3COOH→extConc.H2SO4CH3COOC2H5+H2O\mathrm{C}_2\mathrm{H}_5\mathrm{OH} + \mathrm{CH}_3\mathrm{COOH} \xrightarrow{ ext{ Conc. } \mathrm{H}_2\mathrm{SO}_4} \mathrm{CH}_3\mathrm{COOC}_2\mathrm{H}_5 + \mathrm{H}_2\mathrm{O}
