Name C6H5-O-C(CH3)3: IUPAC Nomenclature

  • Thread starter blitz.km

In summary, the compound C6H5-O-C(CH3)3, also known as Phenyl t-butyl ether, has two possible IUPAC names: 1,1-dimethyl 1-phenoxy ethane and 2-methyl 2-phenoxy propane. The correct name may depend on which naming convention is used, as one uses the smaller 'ethane' while the other uses the longest chain, 'propane'. It is important to consider the main functional group, which is attached to the 2nd carbon of the chain. However, this does not affect the overall name of the compound.

C6H5-O-C(CH3)3

This compound is given in my textbook with its trivial name "Phenyl t-butyl ether".
I tried to write its IUPAC name.. but I am getting confused between these 2 names:

1,1-dimethyl 1-phenoxy ethane
and
2-methyl 2-phenoxy propane

Please help! And explain your answer too.

Do you have a diagram?
 
  • #3
one of your names uses the smaller 'ethane' and the other uses the longest chain, 'propane'. Which do you think is correct?
 
  • #4
Yeah I know we prefer the longest carbon chain.
But here the main functional group is attached to the 2nd carbon of the chain..
so I got confused..
Does that matter?
