(3) 3-methyl-1-butyne and (4) 1-pentene​. Both 3-methyl-1-butene and 1-pentene will not give a precipitate with Tollen's reagent.

Explanation:

Both 3-methyl-1-butene and 1-pentene will not give a precipitate with Tollen's reagent.

An alkaline solution of ammoniacal silver nitrate is known as Tollen's reagent.

The following are tested with it: aldehyde, hydroxy ketone, terminal alkyne. With the aforementioned solutions, it forms a white precipitate when tested.

However, when tested with 1-pentene and 3-methyl-1-butene, it does not produce a white precipitate. Both 3-methyl-1-butene and 1-pentene contain neither a terminal alkyne nor an aldehyde group as well as a hydroxy ketone.

As a result, when tested with the tollen's reagent, it will not precipitate. Tollen's reagent will precipitate silver alkynes when mixed with a terminal alkyne.
