Best Answer

H-O-H

Well, the hydrogens bring a total of two valance electrons to the mix and the oxygen contributes six, so the total valance electrons = 8

4 are used in the two bonds, so 8 - 4 = 4

Two lone pair, one above and one below the oxygen in the Lewis dot structure.

What type of bonding around a central would result in a trigonal planar molecule -apex?

A molecule with a trigonal planar geometry around a central atom typically results from having three bonding pairs of electrons around the central atom, forming a flat triangle. This is commonly seen in molecules with sp2 hybridization, such as those with three sigma bonds and no lone pairs around the central atom.
