Question

which of the following has maximum surface tension

Answer 1

<<Since the options are not given, I am answering the question based on the options given for the same question in another website.>>

The answer is water.

The liquid with the maximum surface tension is water. This is because the hydrogen bonding is maximum between water molecules. Each water molecule is capable of forming four hydrogen bonds with the water molecules near it. Mercury is the only other liquid that has more surface tension other than water.

Answer 2

The question is incomplete.

However,

Surface tension: The minimization of the surface area caused due to the attraction of particles on the surface of the liquid is referred to as surface tension.

The polar property of water makes the molecules attract with each other. The hydrogen ends are positive whereas the oxygen ends are negative.

Water has high surface tension compared to many other liquids. The surface tension of water is estimated to be  72 dynes/cm at 25°C.

Hence, water is the answer.
