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.

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.
