Which nucleophile, when reacted with 1-bromopropane (CH3CH2CH2Br), would produce an ether?


I-
OH-
-OCH3
SH-

To determine which nucleophile would produce an ether when reacted with 1-bromopropane (CH3CH2CH2Br), we need to identify the nucleophile that can participate in a nucleophilic substitution reaction and substitute the bromine atom with an oxygen atom.

In this case, the nucleophile that can form an ether is -OCH3 (methoxide ion). When -OCH3 reacts with 1-bromopropane, it will substitute the bromine atom and form methoxypropane, which is an ether.

The other options, such as I-, OH-, and SH-, do not have the ability to form an ether. I- and OH- can participate in nucleophilic substitution reactions, but they would result in the formation of an alcohol rather than an ether. SH- is a weak nucleophile and would not readily react with 1-bromopropane.

Therefore, the correct nucleophile to produce an ether when reacted with 1-bromopropane is -OCH3.
