Question

It is difficult to type these but I'll do my best. This is the first question and I just don't get it. My professor is out of the country so any help would be appreciated.

Give the IUPAC name for each of the following alkanes:

CH3
I
a. CH3--CH--CH2--CH2--CH3

b. CH3 CH3
CH3--CH--CH--CH3

c. CH3 CH3
CH3--CH2--CH--CH2--CH--CH3

d. CH2--CH3
CH3--CH2--CH--CH--CH2--CH3
I
CH2--CH3

Answer 1

It is difficult to handle spacing on the board; it ignores any spaces after the first one. Try drawing condensed structures for these.
For example, propane is
CH3CH2CH3 and 2-methyl propane would be
CH3CH(CH3)CH3
In general, find the longest chain that includes the most triple/double bonds and name that as the base, then add the groups to that base name.

Answer 2

Ans b-hecsane ans c-octane
