Chapter 1, Problem 13EQ
This is done by removing an unshared pair from each of two adjacent atoms and adding one electron pair as a second bond between the atoms. Each such operation reduces the number of electrons in the trial structure by two. Removing the unshared pairs of electrons on the carbon atoms and adding a second carbon–carbon bond gives
a structure in which there are four electrons involved in a double bond between the carbon atoms. The trial structure now contains electrons ____ and is correct.

Which of these is a hydroxyl group? A large organic molecule with different functional groups. A group marked A consists of a nitrogen atom and two hydrogen atoms attached to it. A group marked B consists of a phosphorus atom with four oxygen atoms. One of these oxygen atoms is connected to the phosphorus by a double bond. All other bonds are single. Two oxygen atoms have negative charges. A group marked C consists of a carbon atom connected to an oxygen atom by a double bond. A group marked D consists of an oxygen atom connected to a hydrogen atom. The group marked E consists of a sulfur atom connected with a hydrogen atom. A group marked F consists of a carbon atom, which is connected to one oxygen atom by a double bond and the other oxygen atom by a single bond. This last mentioned oxygen atom also has a hydrogen attached. EDACF
A. Structural Isomerism of Alkanes, continued.
Construct models for the five alkanes that have the molecular formula C6H₁4. All five of your models should have the same
number of each type of atom, but they should have the atoms connected in a different order. Thus the molecules they
represent are structural isomers of one another. Note the tetrahedral geometry of each carbon atom.
Draw an extended and a condensed structure (NOT skeletal/line angle) of each structural isomer, then determine its IUPAC
name. Recall that since the IUPAC name specifies the number of each type of atom and how they are connected, each
structural isomer will have a different name. Each name should very specifically describe the structure.
