Vinay was trying to create sodium acetate, he added ethanoic acid and ‘A’ in an open vessel. He also added few drops of concentrated H2SO4 to this and was surprised when the solution gave a sweet effervescence. So he repeated this experiment in a closed vessel and obtained ethyl acetate. Then he added ‘B’ and created sodium acetate. Find A and B.

Expert Answer:

Compound 'A; is ethyl alcohol C2H5OH
 
When ethanoic acid is added to  ethyl alcohol (C2H5OH) in the presence of concentrated H2SO4 gives ethyl acetate (CH3COOC2H5

Compound B is sodium hydroxide (NaOH).
 
When ethyl acetate (CH3COOC2H5) is treated with sodium hydroxide (NaOH) it gives sodium acetate (CH3COONa)  as a product.
 
stack CH subscript 3 COOC subscript 2 straight H subscript 5 with ethyl space acetate below space plus NaOH with open parentheses straight B close parentheses below space rightwards arrow with space on top space stack CH subscript 3 COONa with sodium space acetate below space plus straight C subscript 2 straight H subscript 5 OH
