c is obviously wrong, as is d, because if you had a methyl on the end it would be a longer chain name. That makes e wrong.
b How can you put a methyl on the number one carbon without making it a longer chain?
Leaving a) Draw it out on a propylhexane, on one side you have a 2C chain, and on the other, you have a 3chain. If you attach a propyl to number three, you have now from the right a chain of seven, meriting a new name.
So is any of these correct?
which of the following alkane names is correct?
a)2-methyl-3-propylhexane
b)1-methylnonane
c)1,2-dimethylhexane
d)4,5-dimethylpentane
e)all of the above names are correct
PLEASE HELP!!!!GOT STUCK ON IT
