An organic compound A with a molecular formula C2H6O on heating with another acidic compound B in presence of an acid forms a sweet smelling compound C.
a)Identify the name of the reaction
b)Write chemical equation for the above reaction
c) Write chemical equation for the reaction when base is added to compound C
d) write one use of compound C
Answers
Compound A- C2H60 is ethanol
Compound B - CH3COOH is eathanoic acid
Compound C - CH3CH2CH3O is ester
a) The reaction is esterfication....when alcohol and acid reacts they form esters
b) chemical equation
C2H60+CH3COOH=CH3CH2CH3O+H2O
Eathanol + eathanoic acid=ester + water
c) when base (alkaline) is added to ester , it gives back eathanol and sodium salt of carboxylic acid
NaOH + CH3CH2CH3O=C2H60+CH3COONa
Sodium hyroxide + ester= eathanol+sodium acetate
d) Compound be (esters) are sweet smelling substances often used in perfumes
Answer:
2 CH₃COOH + 2 Na ⇒ 2 CH₃COONa + H₂ ↑
( A ) ( B )
CH₃COOH + C₂H₅OH ⇒ CH₃COOC₂H₅ + H₂O
( C ) ( D )
CH₃COOC₂H₅ + NaOH ⇒ C₂H₅OH + CH₃COONa
Therefore we identified
A - CH₃COOH
B - CH₃COONa
C - C₂H₅OH
D - CH₃COOC₂H₅
