उत्तर
Oil and water are two immiscible liquids, which means both of them repel each other. But when we add detergent to a solution containing water and oil, the mixture becomes homogeneous. This happens because of the detergent molecule. The detergent molecules have two ends. One of its ends holds on to a water molecule and the other end holds on to the oil molecule. These opposing forces help in dissolving the oil in water and thus making a homogeneous mixture.
