Choose the incorrect statement regarding the Van der Waals interactions & Hydrogen bonds

1. In Van der Waals interactions greater the area of contact the stronger the interaction.

2. In Van der Waals interactions greater the area of contact the weaker  the interaction.

3. Hydrogen bonds Relative strength is inversely proportional to the polarity More polar atoms form weak H bonds.

4. Hydrogen bonds Relative strength is directly proportional to the polarity More polar atoms form stronger H bonds.

#Unit 1. Molecules and their Interaction Relevant to Biology

As atom "A" approaches, the electrons of atom "B" will be attracted by the positive end of atom "A". As a result, the electrons of atom "B" will migrate to the left side and make the left side slightly negative. This phenomenon can be explained by

Choose the correct statement regarding the Spontaneous dipole - induced dipole interaction 

1. Spontaneous dipole - induced dipole interaction are also known as dispersion or London forces related to orientation effect.

2. The potential energy of an induced dipole-induced dipole interaction is depending on the first ionization energy of the molecule

3. Spontaneous dipole - induced dipole interactions are large networks of intermolecular forces between nonpolar and non-charged molecules and atoms (i.e. alkanes, noble gases, and halogens)

4. In Spontaneous dipole - induced dipole interaction a small increase in the radius, would greatly decrease the potential energy of the interaction.
