A concept map for four types of intermolecular forces and a certain type of bond is shown. (text explanation of the concept map)(An ellipse is shown. Inside the ellipse is written Are ions present. An arrow from the right side of the ellipse has Yes written on it and points to another ellipse. This ellipse has Are polar molecules present written inside it. This ellipse has two arrows coming out of it. One arrow has Yes written on it and leads to a rectangular box that has D written inside it. The second arrow has No written on it and leads to a rectangular box that has E written inside it. An arrow from the left of the topmost ellipse has No written on it and leads to an ellipse that has Are molecules with permanent dipoles present Written on it. An arrow that has No written on it, points from this ellipse towards a rectangle that has A written inside it. An arrow that has Yes written on it, points from this ellipse towards another ellipse that has Is H atom bonded to F, O, or N atom Written on it. This ellipse also has two arrows coming from it. The arrow with Yes written on it leads to a rectangle that has C written on it and the arrow that has No written on it leads to a rectangle that has B written inside it.)

Compare the relative strength of the two forces B and C. Explain how you determined this comparison by identifying the forces.
