boric acid?

Question

# of valence electrons
total # of electrons
# of single bonds

Answer 1

Boric acid is often written as H3BO3 but structurally is best seen as B(OH)3. It has a central Boron atom attached to three Hydroxides (OH-).

Boron usually has 3 valence electrons, Oxygen has 6 and Hydrogen 1.

The total number of electrons in the molecule is 5 + 3*8 + 3*1 = 32 electrons.

The molecule has 6 single bonds: 3 O-H bonds and 3 B-O bonds.
