A
Explanation:
A hydroxide ion is given as:
OH⁻
The electron dot notation shows only the chemical symbol of the element surrounded by dots to represent the valence electrons. The chemical symbol denotes the nucleus and all electrons except the valence electrons.
The dots are arranged on the four sides in pairs.
Oxygen is made up of 6 valence electrons, and since the ion has a net negative charge, the hydrogen and oxygen achieved their stable configuration this way.
The rule of solubility states that, like dissolves like. Water is a polar compound. Hence compound that is most polar, will dissolve maximum in water.
Among to available options, ethanol has maximum polarity. Hence, its solubility will be maximum in water.
Other solvents like benzene, toluene and carbon tetrachloride are non-polar in nature. Hence, they show poor solubility in water.
