Question

Ethyl methyl ketone is obtained by heating calcium salts of
A. formci acid + propoionic acid
B. acetic acid+ propionic acid
C. acetic acid only
D. acetic acdi + methanoic acid

Answer 1

Correct Answer - B
Ethyl methyl ketone is an unsymmetric ketons, so two different acids (in the form of calcium salt) are used. The structure of ethyl methyle ketone is
`C_(2)H_(5)COCH_(3)`
The structure shows the presence of 4 carbon atoms, thus the calcium salts must be acetic acd and propionic acid to form `C_(2)COH_(3)`
`(C_(2)H_(5)COO)_(2)Ca+(CH_(3)COO)_(2)Ca overset("Distil.")to C_(2)H_(5)COCH_(3)+CaCO_(3)`
