Dry distillation of a mixture of calcium salts of formic acid and acetic acid results into the formation of:
Correct answer: B. Acetaldehyde
- A. Formaldehyde
- B. Acetaldehyde
- C. Calcium acetate
- D. Sodium acetate
Explanation
A is incorrect as formaldehyde is a product of calcium salt of formic acid.B is correct as Dry distillation of a mixture of the above calcium salts of acetic and formic acid respectively leads to the formation of an aldehyde. Dry distillation is the process in which the solid materials are heated to produce gaseous products.C is incorrect as calcium acetate is not a product of calcium salts of formic acid and acetic acid.D is incorrect as sodium acetate is not a product of calcium salts of formic acid and acetic acid.

About Preparation of Aldehydes and Ketones
Aldehydes and ketones are prepared mainly by controlled oxidation or dehydrogenation of primary and secondary alcohols, respectively. The topic also includes ozonolysis of alkenes, hydration of alkynes and preparation through acyl derivatives, with attention to why primary alcohols can give aldehydes whereas secondary alcohols give ketones.
