(a)
Interpretation:
The electron-pair geometry for carbon atom in
Concept introduction:
The electron pairs in Lewis diagrams repel each other in real molecule and thus they distribute themselves in positions around the central atoms which are far away from one another. This arrangement of electron pairs is called electron-pair geometry. The electron pairs may be shared in covalent bond, or they may be lone pairs.
(b)
Interpretation:
The molecular geometry predicted by the valence shell electron-pair repulsion theory for the carbon atom in the molecule
Concept introduction:
Molecular geometry is the precise term that is used to describe the shape of molecules and arrangement of atoms around the central atom. The molecular geometry of a molecule is predicted by valence shell electron-pair repulsion theory or in short VSEPR theory. VSEPR theory applies to substances in which a second period element is bonded to two, three, four, or other atoms.

- To answer the questions, interpret the following Lewis structure for SO42-. For the central sulfur atom: ... The number of lone pairs = The number of single bonds = The number of double bonds = The central sulfur atom: obeys octet rules or expanded octet rules or has incomplete octet rules? 2) To answer the questions, interpret the following Lewis diagram for CO2 .For the central carbon atom: ... The number of lone pairs = The number of single bonds = The number of double bonds = The central carbon atom: obeys octet rules or expanded octet rules or has incomplete octet rules? 3) To answer the questions, interpret the following Lewis structure for BCl3. For the central boron atom: ... The number of lone pairs = The number of single bonds = The number of double bonds = the central boron atom: obeys octet rules or expanded octet rules or has incomplete octet rules?arrow_forwardPlease refer to the example image to answer. You must use CER, claim-evidence-reasoning. Make sure that your answer is CLEAR. Claim is your answer to the question. Evidence is from the image and reasoning is your explanation. Proper evidence for all Lewis structures include: Carbon or most electronegative atom in center. Octet of electrons surrounding each atom. Total number of electrons depicted equals same total number of valence electrons from each participating atom. Make sure to refer to the example image. It shows what correct Lewis structures include.arrow_forwardPlease refer to the example image to answer. You must use CER, claim-evidence-reasoning.

Include your steps in creating each sketch. Each diagram should include labelled electronegativities and partial charges for each atom within the molecule, and vector arrows representing the magnitude and direction of each bond dipole and net dipole (for polar molecules). Finally, determine whether the molecule is polar or non-polar and explain your rationale based on bond polarity and molecular shape.
