Propionic acid and ethyl alcohol gives a products, same product can be obtained from which reaction ?

Options

A. Acetic anhydride `+` Ethanol
B. Propionic anhydride `+` Ethanol
C. Acetic anhydride `+ C_(2)H_(5)ONa`
D. Propionic anhydride `+C_(2)H_(5)ONa`

Answer

B

Explanation

`underset("Propiionic acid")(CH_(3)CH_(2)-overset(O)overset(||)(C)-OH)+underset("Ethanol")(C_(2)H_(5)OH)rarrH_(2)O+CH_(3)CH_(2)-overset(O)overset(||)(C)-OC_(2)H_(5)`
`underset("Propionic anhydride")(CH_(3)CH_(2)-overset(O)overset(||)(C)-O-CH_(2)CH_(3))+underset("Ethanol")(C_(2)H_(5)OH)rarrCH_(3)CH_(2)-overset(O)overset(||)(C)-OC_(2)H_(5)+CH_(3)CH_(2)-overset(O)overset(||)(C)-OH`
