Stick Notation for Organic Molecular Structures The molecular structure of (E)-B-damascone is represented below. In such shorthand diagrams, the end of each line segment, if not labelled with a chemical symbol, corresponds to a carbon atom. Hydrogen atoms bonded to carbon are frequently not drawn but are always inferred to complete the valence shell for each C atom. Non-bonding electrons for N and O atoms are also omitted from the diagram but can be inferred to complete those valence shells....

Use Lewis symbols to show the reaction of atoms to form a covalent molecule AsH3. Write the Lewis formula for AsH3 assuming octet rule holds for the atoms. Identify the bonding pairs and lone pairs in the Lewis electron-dot formula of AsH3. Predict the electron arrangement and the shape or geometry of the AsH3 molecule using the VSEPR model.

Draw the Lewis structure with the atoms arranged as HClO. Do not draw Cl with an expanded octet. The formal charge on an atom = number of valence electrons – number of nonbonding electrons – 1/2 × the number of bonding electrons. There should be a total of 14 electrons in each structure and everything should have an octet except for H, which has a duet.

Prelab Assignment You are asked by your instructor to draw the Lewis structure of the NHCI molecule. Being of a conservative nature, you proceed as directed in the Procedure section. 1. First, find the number of valence electrons in NHECI. For counting purposes with Lewis structures, the number of valence electrons in an atom of a main group clement is equal to the last digit in the group number of that element in the Periodic Table. N is in Group...
