Formal charge = (valence electrons) &#8211; (lone pair electrons) &#8211; (1\/2 bonding electrons).<\/li>\n<\/ol>\n\n\n\n<p>Now, let\u2019s go through each of the chemical species in your list:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">A. <strong>HBrO\u2082 (Hypobromous acid)<\/strong>:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Total valence electrons: H (1), Br (7), O (6&#215;2) = 1 + 7 + 12 = 20.<\/li>\n\n\n\n<li>Central atom: Bromine (Br) since it&#8217;s the least electronegative.<\/li>\n\n\n\n<li>Structure: Br forms single bonds with both O atoms and a single bond to H.
