Question

Ethyl alcohol (ch3ch2oh) is/is not soluble in water. 1. is; all organic molecules are soluble in water. 2. is; ethyl alcohol exhibits dipole-dipole and h-bonding interactions with water. 3. is not; ethyl alcohol exhibits dispersion forces which are insufficient for dissolving. 4. is not; ethyl alcohol is an ionic compound with a hydroxide group and hydroxides are insoluble.

Answer 1

Answer:
            Ethyl alcohol is soluble in water because ethyl alcohol exhibits dipole-dipole and h-bonding interactions with water.

Explanation:
                   Ethyl alcohol and water are miscible in each other because both are polar in nature and "Like dissolves Like".
                   The bond between oxygen and hydrogen atoms, both in alcohol and water are polar in nature and results in intermolecular hydrogen bond interactions between them as hydrogen bonding results when hydrogen atom in one molecule directly attached to highly electronegative atoms like fluorine, oxygen and nitrogen forms interaction with higly electronegative atom of neighbor atom.
