How many H-bonds can one water molecule form with other water molecules . 377 Food and Agriculture Organization of the United Nations Acetic acid: 1. The molecule's Lewis structure looks like this As you can see, the central atom is bonded to two oxygen atoms, and no lone pairs are present on it, which means that its steric number will b equal to 2. Lone pairs, Geometry, Shape, Lewis Structure Example, 3d model, bond angles. The convention is to indicate the number of bonding electron pairs by the capital letter X, the number of lone electron pairs by the capital letter E, and the capital letter A for the central atom of the molecule (AXnEm). You should remember that we learned about molecules where the central atom gets more than an octet of electrons. The H2S molecule, for example, has a difference of 0. 105. tertiary.
