CHC13 c Copyright 0 2007, Newton South High School, Newton, MA 02459. Chemistry Worksheet Lewis Dot Structures Name: Block. 2. Draw Lewis structures for the following covalent compounds: H202. C2H5Cl CH30CH3 c- CH20 (carbon is central)
Chem 1020 Lewis structures worksheet. Complete in the following table: For the following neutral molecules, calculate the total number of valence electrons and draw the correct Lewis structure. (For neutral molecules, it’s okay to assume the normal numbers of covalent bonds apply and that the central atom is the first non-H element in the formula.)
Lewis structures are used to model how the electrons are arranged in a covalent molecule. Dots represent electrons and a line between two atoms represents a bond that is formed by a pair of electrons; double and triple bonds are represented by two and three lines respectively.
