Draw a 3D model of CHBrClF and draw a model of the mirror image of your first molecule. What is the relationship between the two models of CHBrClF?

Predicting whether molecules are polar or nonpolar.

a Draw the Lewis structure for CH4 in the window below and then decide if the molecule is polar or nonpolar.

PLease answer all of the questions on the picture and show step by step IN PICTURES, DO NOT TYPE IT! Show all your work and explain.

Answer the questions in the table below about the shape of the sulfur dioxide (SO₂) molecule. How many electron groups are around the central sulfur atom? Note: one "electron group" means one lone pair, one single bond, one double bond, or one triple bond. What phrase best describes the arrangement of these electron groups around the central sulfur atom? (You may need to use the scrollbar to see all the choices.) 0 (choose one) O

For each row in the table below, decide whether the pair of elements will form a molecular compound held together by covalent chemical bonds. If the elements will form a molecular compound, check the box and enter the chemical formula and name of the compound. (If the elements will form more than one molecular compound, use the compound with the fewest total number of atoms.) You may assume all chemical bonds are single bonds, not double or triple bonds. element #1 element #2 carbon iodine hydrogen iodine potassium nitrogen element pair will form a molecular compound molecular compound chemical formula 0 0 П name 0 0 ☐ Ś

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. CH,CH,0H) give the structure around the bold atom.
