The Lewis structure for B(OH)₃is shown in the image attached.
How do you arrive at the Lewis structure of B(OH)₃?
The total valence electrons of B(OH)₃, which is the sum of the three valence electrons of bo//ron, the three hydrogen atoms that contribute one each, and the three oxygen atoms that contribute si/x each, are the initial steps in determining the Lewis structure of the compound.
The element is bo//ron, which is joined by single bonds to three hydrogen atoms. In order to meet the oct//et rule for hydrogen, the remaining electrons are allocated.
A bo//ron atom is bonded to three hydrogen atoms in the final Lewis structure, and three oxygen atoms all of which have lo//ne pairs that surround the atom.
