Alkyl Groups
The most common alkyl groups  ar discussed on this page. (They are excessively shown in example 11 in your workbook.) I would like to point out the similarities among these alkyl groups and the alkanes we discussed earlier.
m ethyl group radical radical Group
Methane has oneness carbon and four hydrogens. The methyl group also has one carbon but except terce hydrogens. In place of the fourth hydrogen, there is a attach to something else.| methyl| H

Ethyl Group
Ethane has two carbons and six hydrogens. If any one of those hydrogens is removed and replaced with a bond to something else, you complete up with an ethyl group.| ethyl| H H

Propyl Groups
Propane has three carbons and eighter hydrogens. If one of the six endhydrogens is replaced by a bond to something else, you end up with anormal propyl radical group. If one of the two middle hydrogens is replaced by a bond to something else, you end up with an isopropyl group.| n-propyl

The skeletal structural formulas shown here are intended to emphasize the fact that the n-propyl and isopropyl groups can be cadaverous in a variety of orientations.



It is non the way that the Cs are drawn that makes the difference. It is the location of the bond to something else that distinguishes n-propyl from isopropyl. Starting from the adhere point in anormal propyl group there is a continuous string of three carbon atoms. Starting from the bond point in an isopropylgroup the three carbon atoms are not continuous, instead they are branched.| n-propyl| isopropyl|

In these skeletal formulas the hydrogen atoms down been left off, just to emphasize the relationships of the carbon atoms. Keep in mind that every carbon atom has four bonds and if only one bond is shown, it is implied that the other three bonds go to three hydrogen atoms.
