The electron-pairs of double bonds would occupy two of the equatorial sites to reduce repulsive forces, similar to that of lone pairs. Symmetry Point Groups. Bis(benzene)chromium C12H12Cr 6. The point group assignment depends on how the pairs of spokes (attached to both the front and back of the hub) connect with the rim. A point group is defined by properties which describe the criteria that a point must match to belong to a point group, such as its point number, its name, its raw or full description, or its elevation. Assign the point group for H3O^+ and NH4^+ respectively. Drawing the Lewis Structure for H 3 O + Video: Drawing the Lewis Structure for H 3 O + For the H3O+ Lewis structure we first count the valence electrons for the H3O+ molecule using the periodic table. This is equivalent to saying that a n-fold rotation converts an object into its mirror image. I think you mean "something acts as acid towards a compound if it protonates that compound". - H2O reacts as an acid and forms HO-, or reacts as a base and forms H3O+ - HCO3- reacts as an acid and forms CO3 2-, or reacts as a base and forms H2CO3 .
