The forces between the water molecules are called as the hydrogen bonding, while the forces of attraction between the ethanol molecules are dipole-dipole forces. Along, with the alignment or arrangement of the surface molecules makes it very clear to know more about the characteristics of the water and ethanol molecules, and the way they behave when any number of insects walk across these surfaces. So, the water characteristics makes it more easy to understand that the insects will find it more easy to walk on the surface of the water medium just because of the capacity of the molecules to with hold the amount of insects weight in a given parameter. And thus water surface is suitable for an insect to walk on rather then walking on the surface of ethanol.So, its all about the surface tension of the water medium that provides us with an option for the insect to travel on it surface.

Water and ethanol two different mediums:

The two different mediums represents a more different form or nature to a insect when it comes to letting it to walk over its surface. As there are different forms of bonding inside the molecules of the two different mediums, the ethanol has the dipole-dipole forces between its molecules making it much weaker to support for lifting the total weight of the insect present on its surface.

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
