Question #650f9

Answer 1

The the preferred IUPAC name (PIN) is 2-ethoxypropane.

Explanation:

(a) The systematic name

Name it as an alkoxyalkane.

(I) Choose the longest continuous carbon chain

`"C-C-C"` = propane

(ii) Name the side chain

`"CH"_3"O-"` = methoxy

This gives methoxypropane.

(iii) Locate the group on the main chain

`stackrelcolor(blue)(1)("C")"-"stackrelcolor(blue)(2)("C")"-"("OCH"_3)stackrelcolor(blue)(3)("C")`

The group is on `"C2"`, so the PIN is

2-methoxypropane

(b) The functional group name

Name the alkyl groups in alphabetical order followed by the word "ether".

The groups are `"CH"_3"-"` methyl and `"-CH"("CH"_3)_2` isopropyl.

This gives an acceptable IUPAC name:

isopropyl methyl ether.
