QUESTION 5 Determine which compound should have a(n) linear molecular geometry. Key Concept: Lewis structures are drawn from a knowledge of the total number of electrons from all the atoms involved in the structure. The element with the lowest electronegativity is the central atom. Fulfill octet of outside atoms first. Molecular shape depends upon the number of atoms and lone pair electrons around the central atom. A H3O+ B ClF2+ C IF2- D AsF5
Predict the shape of CCl2H2based on VSEPR theory. Show your work using Lewis dot structure. Central atom is in Bold. After drawing the Lewis structures answer the following. CCl2H2 Central atom Number of bonds to the central atom Nonbonding pairs on the central atom Total bonds + nonbonding pairs Shape of the molecule
please draw a lewis structure, determine the # of electron groups around the central atom, and determine the geometry of the molecule. (please state both the name of the geometry and draw the molecular shape) molecule lewis structure electron pair geometry around the central atom(s) molecular shape around the central atom(s) CO2 H2S H2O2 NF3 SO2Cl2 NO2 C2H2 C2H4 C2H6
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
The compound XeCl2F2 can exist in two different forms. One form is polar and the other form is non-polar. Draw a valid Lewis structure of XeCl2F2. Then, draw two 3-dimensional representations of this molecule (including all lone pairs); one that shows the polar form with a correct dipole arrow and the other that shows the non-polar form of the molecule.
To draw a Lewis Structure, start with the atomic symbol in the middle, then put dots around the symbol until all of the valence electrons are represented. Try to envision a box around the atom symbol, and the electrons on each side of the box. The valence electrons should be drawn around the element symbol one on each side before pairing the electrons up. The maximum number of electrons that could be on one side of a Lewis Structure is two, and the maximum number of electrons around an element symbol is eight. To figure out how many valence electrons each element has, use the Periodic Table. Remember, the number of valance electrons for Group A elements is equal to the Group A number the element is in on the Periodic Table. Use the data you collected in Table 1 to a draw Lewis structure model to show the formation of any one of the compounds you assembled, then explain the model you drew. Remember, you should be explaining and supporting your answers by referencing and citing the…
Which one of the following statements is FALSE? A) In a polar covalent bond, the electrons in the bond will be closer to the more electronegative atom B) In a nonpolar covalent bond, the electrons in the bond are equally balanced between the two atoms C) In a bond between boron and hydrogen, the electrons will be unequally shared D) A bond between nitrogen and oxygen will be polar E) In a bond between magnesium and sulfur, the electrons will be shared and closer to the sulfur
How do you determine whether a molecule is polar? Select all that apply. 1) Determine if the bonds are ionic or covalent. 2) Draw the Lewis structure for the molecule and determine the molecular geometry. 3) Determine whether the molecule contains polar bonds. 4) Determine whether the polar bonds add together to form a net dipole moment.
Identify the errors in each of the following Lewis structures and draw the correct formula. Draw the correct Lewis structure of this molecule by placing atoms on the canvas and connecting them with bonds. Include all hydrogen atoms and lone pairs of electrons.
Write a Lewis structure for each of the following molecules that are exceptions to the octet rule. ClO2 Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons and nonbonding electrons. Do not include charges.
Please note that "geometry" refers to the molecular or ionic geometry. Recall that for predicting geometry, double and triple bonds count as only one electron The Lewis diagram for CS₂ is: [Review Topics] [References] Use the References to access important values if needed for this question. S=C=S The electron-pair geometry around the C atom in CS₂ is There is/are lone pair(s) around the central atom, so the geometry of CS2 is The Lewis diagram for NO₂¯ is: —N= N=Ö: 0: The electron-pair geometry around the N atom in NO₂ is There is/are lone pair(s) around the central atom, so the geometry of NO₂ is attempts remaining
NO3 Sketch the proper Lewis structure for this substance. Be sure to follow octet/duet rules for each atom and use the total number of valence electrons available. Use your drawing to answer the following questions. Count the total number of electron domains surrounding the central atom. Enter the value only. Enter the name corresponding to the electron domain geometry. Choices are: linear, trigonal planar, or tetrahedral. Enter the name corresponding to the molecular geometry. Choices are: linear, trigonal planar, tetrahedral, bent, or trigonal pyramidal. Predict the bond angle. Enter the value without units. Use a "<" if needed.
