Question

Give the IUPAC name of the above mentioned ether (t-butyl propyl ether).

Hint:

Name the ether as an alkoxyalkane: the larger group (t-butyl) is the parent chain, the smaller group on oxygen is propoxy.

Answer 1

Step 1: Write the structure.
t-Butyl propyl ether is $\mathrm{(CH_3)_3C{-}O{-}CH_2CH_2CH_3}$, with a tertiary butyl group on one side of oxygen and an n-propyl group on the other.

Step 2: Choose the parent chain.
In the alkoxyalkane system, the side with more carbon atoms is the parent chain. The t-butyl side has 4 carbons, the propyl side has 3. The parent is the longest chain on the t-butyl side, which is propane, and the one extra carbon is a methyl branch on C-2.

Step 3: Name the substituents.
C-2 holds the methyl group and the oxygen link. The group on oxygen is $\mathrm{CH_3CH_2CH_2{-}O{-}}$, named propoxy. Arranged alphabetically it is methyl, propoxy.

Final Answer:
The IUPAC name is 2-methyl-2-propoxypropane.
\[ \boxed{\text{2-Methyl-2-propoxypropane}} \]
