Answer 2

Dear Student,

◆ Answers -

(a) Chemical names -

1. CH3-CO-CH3 = Propanone (aka acetone)
2. C2H5-COOH = Propanoic acid (aka propionic acid)

(b) When acetic acid and ethanol react in presence of conc.H2SO4, ethyl ethanoate is formed. This is called esterification. Water is formed as byproduct in this reaction.

CH3COOH + CH3CH2OH --> CH3COOCH2CH3 + H2O

Thanks dear. Hope this helps you...
