Which of the following has the highest induced dipole interactions in its molecule? a. He
b. Ar
c. Ne
d. Kr

Option A

Explanation:

In Dipole -induced dipole forces/interactions a polar and a non polar molecule group together to form a bond.  

The higher is the electronegativity, the higher is the Dipole-Induce dipole.

As electronegativity defines the ability of an atom to attract a pair of electron in any chemical bond.  

The smaller the atom, the higher is the electronegativity and hence the higher is the Dipole -induced dipole forces/interactions

Option A

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
