Answer

(a) Conversion of Ethanol to Carbon dioxide by burning:

C2H5OH ethanol+3O2⟶2CO2+3H2O\underset{ \text{ ethanol}}{\text{C}_2\text{H}_5\text{OH}} + 3\text{O}_2 \longrightarrow 2\text{CO}_2 + 3\text{H}_2\text{O}

(b) Conversion of Ethanol to Ethanal to Ethanoic acid by oxidation using acidified K2Cr2O7:

C2H5OHethanol→K2Cr2O7[acidified][O]CH3CHOethanal→K2Cr2O7[acidified][O]CH3COOHethanoic acid\underset{ \text{ethanol}}{\text{C}_2\text{H}_5\text{OH}} \xrightarrow[\underset{\text{[acidified]}}{\text{K}_2\text{Cr}_2\text{O}_7}]{\text{[O]}} \underset{\text{ethanal}}{\text{CH}_3\text{CHO}} \xrightarrow[\underset{\text{[acidified]}}{\text{K}_2\text{Cr}_2\text{O}_7}]{\text{[O]}} \underset{ \text{ethanoic acid} }{\text{CH}_3\text{COOH}}

(c) Conversion of Ethanol to Sodium ethoxide using sodium:

2C2H5OHethanol+2Na⟶2C2H5ONasodium ethoxide+H2\underset{\text{ethanol} }{2\text{C}_2\text{H}_5\text{OH}} + 2\text{Na} \longrightarrow \underset{\text{sodium ethoxide} }{2\text{C}_2\text{H}_5\text{ONa}} + \text{H}_2

(d) Conversion of Ethanol to Ethyl ethanoate using ethanoic acid and conc. H2SO4:

C2H5OHethanol+CH3COOHethanoic acid→Conc. H2SO4CH3−COO−C2H5ethyl ethanoate+H2O\underset{\text{ethanol}}{\text{C}_2\text{H}_5\text{OH}} + \underset{\text{ethanoic acid}}{\text{CH}_3\text{COOH}} \xrightarrow{\text{Conc.

(e) Conversion of Ethanol to Ethene using conc. H2SO4 at 170°C:

C2H5OHethanol→170°CConc. H2SO4[excess]C2H4ethene+H2O \underset{\text{ethanol}}{\text{C}_2\text{H}_5\text{OH}} \xrightarrow[170\degree\text{C}]{\underset{\text{[excess]}}{\text{Conc. H}_2\text{SO}_4}} \underset{ \text{ethene}}{\text{C}_2\text{H}_4} + \text{H}_2\text{O}\

(a) Conversion of Ethanoic acid [acetic acid] to Sodium acetate using alkali - NaOH:

(b) Conversion of Ethanoic acid [acetic acid] to Calcium acetate using alkali - Ca(OH)2:

2CH3COOHAcetic acid+2Ca(OH)2⟶(CH3COO)2CaCalcium Acetate+2H2O2\underset{\text{Acetic acid}}{\text{CH}_3\text{COOH}} + 2\text{Ca(OH)}_2 \longrightarrow \underset{\text{Calcium Acetate}}{\text{(CH}_3\text{COO)}_2\text{Ca}} + 2\text{H}_2\text{O}

(c) Conversion of Ethanoic acid [acetic acid] to Ammonium acetate using alkali - NH4OH:
