Due to the small and highly electronegative nature of fluorine, the oxyacids of the this element are much less common and less stable than those of the other halogens. bonding theory, however, does allow one to propose structures for these acids and use formal charges for the evaluation of these structures. for a molecule of fluorous acid, the atoms are arranged as hofo. (note: in this oxyacid, the placement of fluorine is an exception to the rule of putting the more electronegative atom in a terminal position.) what is the formal charge on each of the atoms? enter the formal charges in the same order as the atoms are listed. express your answers as charges separated by comma. for example, a positive one charge would be written as +1.

Formal Charge for H, O, F, O = 0,0,1,-1

While an octet of electrons is attained by the oxygen and fluorine atoms in this structure and the formal charges add to zero, having to assign a formal charge of +1 to such an electronegative atom as fluorine may indicate that such a structure is not likely to occur. In fact, fluorine commonly only forms one oxyacid, HOF.

Explanation:

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
