As with any functional group there is a list of rules that must be followed for naming alkanes. 

Naming Alkanes

Concept #1: Rules for Naming Alkanes

Example #1: Naming the following alkane compound. 

Example #2: Naming the following alkane compound. 

Example #3: Naming the following alkane compound. 

Example #4: Determine the structure for the following alkane compound.

3, 4, 5-trimethyldecane 

Example #5: Determine the structure for the following alkane compound.

4-tert-butyloctane

Example #6: Determine the structure for the following alkane compound. 

1-bromo-2,3-dichlorocycloheptane

Additional Problems
Name the following alkane.  
Name the following alkane.  
Name the following organic molecule.  
Name the following organic molecule.  
Alkanes are fully saturated hydrocarbons that end with the suffix –ane. Based on the number of carbons present there is also a set of alkane prefixes that must be used. In the chart below fill in the alkane prefix name based on the number of carbons stated.  
Alkanes are compounds that contain only carbons and hydrogens single bonded to one another. They are sometimes referred to simply as “saturated” hydrocarbons. State the names of the first 10 alkanes.  
NAMING ALKANES When naming any alkane compound there is a set of rules you should follow to get the correct answer. Find the longest carbon chain and assign a root name accordingly. If there is a tie between longest chains, choose the chain that gives _____________ substituents. Number the chain from the end closest to a substituent. Substituents will be named alphabetically and a number will accompany the location of their attachment. If more than one of a similar alkyl group is present then we must use numerical prefixes to describe the number of them. __________ – 2                __________ – 3                __________ – 4                __________ – 5  
Name the following alkanes.    
 Determine the structure for each of the following compounds. a) 4-tert-butyloctane     b) 3,5-dichloro-4-ethylnonane
Name the following cycloalkanes. 
Which of the following is one possible form of pentane? A) CH3CH2CH2CH2CH3 B) CH3CH2CH2CH2CH2CH3 C) CH3CH = CHCH2CH3 D) CH3CH2-O-CH2CH2CH3 E) CH3CH2CH2CH2CH2NH2
Name the following cycloalkanes. 
Name the following alkanes. 
What is the IUPAC name of CH 3CH2CH2CH3?

Alkane Prefixes: Alkanes are fully saturated hydrocarbons with the molecular formula CnH2n+2 that end with –ane. The name of alkanes is based on the number of carbons in the compound. These alkane “prefixes” must be memorized in order to name more complex structures.  
The organic compound CH3CH2CH3 is called1. butane.2. methane.3. ethane.4. pentane.5. propane
CH3CH2CH(CH3)CH(CH3)CH2CH3 Name the Alkane and express the answer in IUPAC name.
