Two statement are given below:
Statement I : The melting point of monocarboxylic acid 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 increases in molar mass.
Choose the most appropriate options

Correct Option - 1
Detailed Solution:Melting point of monocarboxylic acids with even number of carbon is more than that with odd number of carbon due to lattice energy.
With increase in molar mass of monocarboxylic acids size of alkyl group (Hydrophobic portion) increases and therefore solubility in water decreases.
