Ethyl methyl ketone is obtained by heating calcium salts of

Answer»

formic acid + propionic acid
ACETIC acid + propionic acid
acetic acidonly
acetic acid + methanoic acid

Solution :ETHYL methyl ketone is an unsymmetric ketone , so two different acids (in the form of calcium salt) are used . The structure of ethyl methyl ketone is
`C_(2)H_(5) COCH_(3)`
The structure shows the presence of 4 CARBON atoms , thus the calcium salts must be of acetic acid and propionic acid to form `C_(2)H_(5)COCH_(3)` .
`(C_(2)H_(5) COO)_(2) Ca + (CH_(3)COO)_(2) Ca overset("Distill")(to) C_(2)H_(5)COCH_(3) + CaCO_(3)`
