Change the bond between the two carbon atoms in each molecule to a double or triple bond as needed to complete the structure If the bond should remain a single bond, then you do not need to do anything to the bond. Do not change any other bonds in the molecules.

Draw the Lewis structure for OSiS before answering the following questions (You do NOT submit a picture just answer the questions). Silicon is the central atom and all atoms obey the octet rule. WARNING:  Do NOT USE the internet or other sources  to find the structures. Use ONLY the rules taught in class. ALL atoms obey the octet rule Answer the following questions for the  Lewis structure for OSiS , given that silicon is the central atom and all atoms obey the octet rule. Give answers as numbers (1,2,3 ...etc.) NOT words (one, two three etc.)   How many double bonds exist in this structure  How many electrons surround the silicon atom  How many lone pairs are around the silicon atom  How many lone pairs are around the sulfur atom  How many lone pairs are around the oxygen atom  How many electrons surround the Sulfur atom

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 calcium hydrogen sulfur carbon bromine bromine element pair will form a molecular compound molecular compound chemical formula 0 U 1 name 10 17 X 02 Ś

Following is a molecule with polar bonds whose shape was obtained using the VSEPR theory. Specify the molecular shape of this molecule, and whether the molecule is polar or nonpolar. (Hint: In terms of polarity, see whether the dipoles in the molecule cancel or not. A molecule containing polar bonds can be nanpolar if the dipoles cancel each other. You can imagine the dipoles as ropes pulling on the central atom–If the pulls cancel each other, that is, the central atom cannot move, then the molecule is nonpolar. If on the other hand the opposite is true, then the molecule is polar.) O trigonal pyramidal shape, nonpolar O trigonal planar shape, nonpolar O tetrahedral shape, polar O trigonal pyramidal shape, polar O trigonal planar shape, polar

Electronegativity is the ability of an element to pull electrons towards itself in a bond. In a bond, the atom with the greater electronegativity will have a partial charge, and the atom with the lower electronegativity will have a partial charge. Fluorine has the higher/lower electronegativity and Francium has the higher/lower electronegativity. Metals like to gain/lose electrons, while nonmetals like to gain/lose electrons. Thus, metals have a electronegativity, while nonmetals have a electronegativity. a. negative b. positive c. lower d. higher e. lose f. gain g. the same h. none of these

1. Draw the best Lewis dot structure for the anion CCI in the correct molecular geometry [Include formal charges and lone pair electrons, and use dashed and solid wedge bonds if necessary 2. How many electron groups are present around the central atom and what is the electron group geometry? 3. What is the molecular geometry and ideal bond angles? 4. Is the molecule polar or nonpolar? If it is polar, draw a dipole moment arrow next to your structure to indicate the directionality of the dipole moment.
