Hint :The immiscible liquid does not dissolve in each other. Kerosene and water are immiscible liquids. We call things similar if they dissolve in each other, and dissimilar if they don’t dissolve each other. By knowing this concept we can easily solve this question.
Complete Step By Step Answer:
We know that like dissolves like but hydrocarbons are unlike water.
Hydrocarbons tend to possess even distributions of electrons and the electrons at the surface of the molecules all have about an equivalent density, in order that they feel comfortable next to a molecule that is similar to it.
While water, on the opposite hand, features a big distribution of charge. Oxygen is more electronegative than hydrogen, therefore a polarity develops. In liquid water, this separation of charge causes molecules to stay together by their oppositely charged regions and hydrocarbons don't have anything similar.
Hydrocarbon molecules are not stabilized by sticking to at least one another that they are going to open up on a surface. This suggests they need low physical phenomenon and low surface energy. Water, on the opposite hand, has enough polarity to draw in its molecules one to another; it's a high physical phenomenon and high surface energy.
It takes something special to push two water molecules apart
Sometimes I feel we call things similar if they dissolve in each other, and dissimilar if they don’t dissolve. Therefore, kerosene does not dissolve in water hence it is called immiscible liquids.
Hence the correct answer is the option (A).
Note :
Kerosene doesn’t dissolve in water because it’s lighter than water. So, it forms a layer above water. Hydrocarbons can’t roll in the hay - they only spread everywhere the surface and don’t go inside the mass of water.
