Chemistry Question on Bohr’s Model for Hydrogen Atom
Which of the following carboxylic acid is highly insoluble in water?
A
(A) Propanoic acid
B
(B) Butanoic acid
C
(C) Pentanoic acid
D
(D) Decanoic acid
Answer
(D) Decanoic acid
Explanation
Solution
Explanation:
Higher carboxylic acids are insoluble in water due to the increased hydrophobic interaction of the hydrocarbon part. Thus, decanoic acid is highly insoluble in water, as it contains longer hydrocarbon chain.Decanoic acid is a ten-carbon, saturated fatty acid. It is present in palm kernel, coconut fat and in milk fat.Hence, the correct option is (D).
