HintAnswer
To synthesize a secondary propargyl alcohol, react an acetylide anion with a aldehyde and then perform an acid work-up.
In the mechanism of reducing an alkyne to an alkene, one step involves the transfer of a single electron from the sodium metal to the alkyne.
An aldehyde may be synthesized from a terminal alkyne using HgSO4, H2SO4, and water.

To synthesize an acetylide anion, NaOMe may be used for deprotonation.
To synthesize a trans alkene from the corresponding alkyne, use dissolving metal reduction conditions.

Addition of excess HCl to an alkyne results in the formation of a geminal dihalide.

The base NaNH2 is strong enough to deprotonate 2-hexyne.

Ozonolysis of an internal alkyne will yield carboxylic acids.

2-pentyne may be synthesized from acetylene, a base, and 1-bromopropane.

2-methylpropene is a good reagent to use to probe if a reaction is regiospecific.
C10H16 reacts with 1 equivalent of H2 upon catalytic hydrogenation. Ozonolysis of this molecule results in the formation of two carbonyls.

Ozonolysis may be used to determine if an alkene were cis or trans.
In order to synthesize (3R,4S)-3,4-dibromohexane from 3-hexyne, one would reduce the alkyne to an alkene using H2/Lindlar's and then add Br2/CCl4.

There is no such molecule called cyclohexyne.
Hydration of unsymmetrical internal alkynes using HgSO4, H2SO4, and water will result in the formation of two isomeric ketone products.

Keto-enol tautomerization is synonymous with resonance.

The molecule cis-cyclohexene should not exist.
