NamingCurrent LectureAlkyl GroupsAlkyl Group – Alkanes with a hydrogen atom removed and are attached to a straight chain hydrocarbon*REMEMBER THE ALKYL GROUP NAMES. MAKE FLASHCARDS!!!!* (listed below in the third column of the chart)- Went over how to name a compound with a single Alkyl group last lecture, but what if there are 2 Alkyl groups?1. Go through the same naming process (described in Lecture 8 notes), but identify and number both Alkyl groups2. If one methyl group is on the second carbon, a butyl group is on the third, and another methyl group is on the fourth, and the parent chain has 5 carbons, you would name it like this… (Remember to go in Alphabetical order) 3 – Butyl- 3,4 – diMethyl - Pentanehttps://www.google.com/search?q=alkyl+group+chart&es_sm=93&tbm=isch&tbo=u&source=univ&sa=X&ei=bNckVMrRL5PygwS8hILwDw&ved=0CB8QsAQ&biw=1517&bih=714&dpr=0.9#facrc=_&imgdii=_&imgrc=QCbh0vIlSPkaKM%253A%3BljCt55fTWHD1dM%3Bhttp%253A%252F%252F3.bp.blogspot.com%252F_xNuly1lFBfc%252FS9uCpsGXmCI%252FAAAAAAAAAF4%252FWmbWlZH8TN8%252Fs1600%252Fchem.bmp%3Bhttp%253A%252F%252Fchemblog11.blogspot.com%252F2010%252F04%252Forganic-chemistry-april-30-2010.html%3B677%3B242CYCLOALKANESCycloAlkanes – Basically, these are regular alkanes, but instead of being in a line, they are circularEX.https://www.google.com/search?q=alkyl+group+chart&es_sm=93&tbm=isch&tbo=u&source=univ&sa=X&ei=bNckVMrRL5PygwS8hILwDw&ved=0CB8QsAQ&biw=1517&bih=714&dpr=0.9#tbm=isch&q=cycloalkanes&spell=1&facrc=_&imgdii=_&imgrc=yezLiTAM0d3itM%253A%3BjyMIbop-NZg5qM%3Bhttp%253A%252F%252Fupload.wikimedia.org%252Fwikipedia%252Fcommons%252F4%252F49%252FFirst_four_cycloalkanes.png%3Bhttp%253A%252F%252Fcommons.wikimedia.org%252Fwiki%252FFile%253AFirst_four_cycloalkanes.png%3B759%3B214To name cycloalkanes, simply put Cyclo- in front of the parent chain name. - EX. The parent chain name is heptane (7 carbons). To name this one, it would be CycloheptaneWhen naming a blank cycloalkane, identify any alkyl groups on the cycloalkane, then number the cycloalkane, and name it as you usually would.- EX.(The iodo thing will be explained shortly)http://chem1180.blogspot.com/Reactions of Alkanes and CycloalkanesCombustion reactions- Every family has combustion reactions; reactions where the products arewater and carbon dioxide (CO2)(Mono)Halogenation – addition of a halogen to an alkane; basically the C gets rid of an H+ ion and takes a halogen (F, Cl, Br, or I) in its place- The name of a halogenation reaction can be changed based on what halogen is being used.EX. Bromenation for Bromine- To name a Alkane with a halogen on it, simply add an –o to the end of the ionEX. Bromo, Flooro, Chloro, iodo EX. You have a parent chain of pentane with a Cl molecule on the second Carbon. The name would be… 2- chloro
