They are important reagents in organic synthesis, and are frequently used to transfer the organic group or the lithium atom to the substrates in synthetic steps, through nucleophilic addition or simple deprotonation. Our purpose in this chapter is to be able to represent the structure of a molecule. Many planets in our solar system contain organic chemicals including methane (CH 4) and traces of ethylene (C 2 H 4), ethane (C 2 H 6), propyne (H 3 CCCH), and diacetylene (HCCCCH). Write the Lewis structures for each of these molecules. Its Lewis Structure is: There is no single central atom for the molecule, but there are three carbons. C3 is directly bonded to four other atoms (C2 and 3 … This group of compounds is a homologous series with the general molecular formula of C n H 2 n‐‐2 , where n equals any integer greater than one. The 2D chemical structure image of 3-Octyne is also called skeletal formula, which is the standard notation for organic molecules.
