Question

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. Draw a complete Lewis structure of the molecule and answer the following questions. Complete the structure by adding ONLY hydrogen atoms to carbon atoms where needed. You must not create any other bonds. Atoms such as oxygen or nitrogen may have lone pairs to complete their octets. 10 05 2 3 12 6 13 Each of the non-hydrogen atoms of this skeletal structure has been randomly numbered. Match the atom number with the orbital hybridization invoked for sigma bonding. sp38 sp39 vo 2

Answer 1

From the skeleton structure of compound

CH2 groups = 3

CH group = 2

C without hydrogen = 4
