1 Dipole Forces Water is a polar molecule. It has an electric dipole strength of p-6-10-30 С . m. This is roughly equivalent to a proton and an electron separated by a distance of d- 4 10-11 m (about the radius of a hydrogen atom) In this problem, we will use Coulombs law to compare the force between two protons, a proton and a water molecule, and two water molecules. Use the arrangement of the charges shown in the figure for your calculations. (a) What is the force between two protons separated by a distance of r 0.1 nm? (b) What is the force between a proton and a water molecule separated by a distance of r-0.1 nm? (c) What is the force between two water molecules separated by a distance of r0.1 nm? (d) Repeat the analysis of parts (a)-(c) for a separation of r 1 nm. (e) Critical Thinking: You should now have six differ ent numbers. What do they tell you? Compare ratios of various pairs of numbers and comment on the relative strength of the interactions (charge-charge, charge-dipole dipole-dipole and how these depend on distance

    An electric field can induce an electric dipole in a neutral molecule (or atom) by pushing the positive and negative charges inside the molecule in opposite directions. The dipole moment of the induced dipole is directly proportional to the electric field at the molecule. That is, p⃗ =αE⃗ , where  p⃗   is the induced dipole moment, α is called the polarizability of the molecule, and  E⃗  is the electric field at the molecule. A stronger electric field at the molecule results in a...

    Problem 10: The potassium bromide (KBr) molecule has an electric dipole moment of 3.50 × 10 -29 C⋅m. The molecule has a dipole moment because the lone 4s electron of the potassium atom spends much of its time orbiting the bromine nucleus (and thereby filling the 4p shell of bromine) – leaving the potassium atom positively charged and the bromine atom negatively charged (this is called “ionic bonding”). (a) Assuming for the moment that the potassium 4s electron spends all...
