6. Methanoic acid (look it up in the book) has one carbon-oxygen bond of 1.36 Angstroms, and one
of 1.23 Angstroms. The methanoate ion (the product of the acid giving up the hydrogen) has
two identical C-O bonds. Explain this using Lewis structures.
7. Dissolving a c
Step 1 – Write the Lewis structure from the molecular formula.Step 2 – Assign an electron-group arrangement by counting all electron groups (bonding plus nonbonding) around the central atom (or around each centralatom, if more than one central atom in structure).Step 3 – Predict the ideal bond angle from the electron-group arrangement and the effect of any deviation caused by lone pairs or double bonds.Step 4 – Name the molecular shape by counting bonding groups and nonbonding groups separately.Step 5 – Predict whether the molecule is polar or nonpolarStep 6 – Describe the hybridization around the central atom and identify the total number of σ and π bonds in the structure
- Draw Lewis structures for each of the following. Give the total number of valence electrons,
select from the lists the number of Regions of Electron Density (REDs) around the central atom,
the molecular shape, and the bond angles.
- Do not put covalent bonds between metals and nonmetals.
- Put brackets around anions to show both charge and quantity.
