Is it correct or wrong

i think correct

Explanation:

i am not sure but i hope it will help you

The correct answer is (A).

Explanation :

that is dimethyl ether will be least soluble in water because extent of hydrogen bonding interaction with water molecules are weakest in comparison to other listed options.

Where as :

In that is ethanol,in which extent of inter-molecular hydrogen bonding with water molecules will be highest due to the presence of polar (-OH) group.Where as () group is less polar than that of the (-OH) group.in that is methyl amine in which extent of hydrogen bonding will higher than than that of the that is ethanal. This is due to presence of two hydrogen atoms in primary amine which are available for inter-molecular hydrogen bonding with water molecules.

So, the order  of solubility from least soluble to highly soluble compound in water will be:
