Determine the electron pair geometry (EPG), the molecular geometry (MG), the bong angle (BA), and the polarity of SiF3. NOTE: Be sure to enter in your answers with correct spelling, spacing, and all lowercase letters; for the bond angle just type in the number; for the polarity enter "yes" for polar and "no" for nonpolar. ЕPG: MG: ВА: polar? enter yes or no:

Draw the 2D and the 3D Lewis structure for each molecule. You do not need to show resonance structures here. Determine the electron pair geometry (EPG), the molecular geometry (MG), the bond angle (BA) around the central atom, and the hybridization of the central or bold atom. Circle the formula of any polar molecule. For molecules with more than one central atom (e.g. CHCH20H) give the structure around the bold atom.

Imagine you are a CHML 201 instructor. One of your students asks “Why is water, H2O, a bent molecule (in other words, why is water’s molecular shape bent with an angle of ~105o)? Why isn’t water a linear molecule?” Answer the student’s question clearly, completely, and in detail – starting from the electronic structure of H and O atoms. A Periodic Table and a Table of Electronegativity values are given above.

Determine the electron pair geometry (EPG), the molecular geometry (MG), the bond angle (BA) around the central atom, and the hybridization of the central or bold atom. Circle the formula of any polar molecule. For molecules with more than one central atom (e.g. CH,CH,0H) give the structure around the bold atom.

Determine the electron pair geometry (EPG), the molecular geometry (MG), the bong angle (BA), and the polarity of BrF5. NOTE: Be sure to enter in your answers with correct spelling, spacing, and all lowercase letters; for the bond angle just type in the number; for the polarity enter "yes" for polar and "no" for nonpolar. ЕPG: MG: BA: polar? enter yes or no:

For each compound in the table below, decide whether there would be any hydrogen-bonding force between molecules of the compound, or between molecules of the compound and molecules of water. compound hydrogen-bonding force Between Between molecules of formula or Lewis the compound and molecules of water? name molecules of the structure compound?
