Two statements are given below :
Statement I : The melting point of monocarboxylic acid with even number of carbon atoms is higher than that of with odd number of carbon atoms acid immediately below and above it in the series.
Statement II : The solubility of monocarboxylic acids in water decreases with increase in molar mass.
Choose the most appropriate option :
Multiple Choice Options
- A Both Statement I and Statement II are correct.
- B Both Statement I and Statement II are incorrect.
- C Statement I is correct but Statement II is incorrect.
- D Statement I is incorrect but Statement II is correct.
Step-by-Step Verified Solution
Statement (I) is correct as monocarboxylic acids with even number of carbon atoms show better packing efficiency in the solid state, statement (II) is also correct as the solubility of carboxylic acids decreases with an increase in molar mass due to increase in the hydrophobic portion with an increase in the number of carbon atoms.
