The following reaction series is completed: (1) 1-butyne is reacted with lda. (2) the organic product of reaction (1) is reacted with a two carbon epoxide. (3) the resulting product is treated with dilute acid. provide the iupac name of the final major organic product expected after step #3. for credit, the spelling and punctuation of your iupac name must follow the rules.

The IUPAC name of compound would be  Hex-3-yn-ol

Explanation:

When butyne is treated with LDA  it leads to generation of carbanion  on the terminal alkyne.

As LDA is disopropyl amide which happens to be quite a good base and hence it is sufficiently basic to abstract the acidic proton on the terminal alkyne.

So this proton abstraction leads to generation of a carbanion which can now acts as a nucleophile in step 2.

In step 2 the generated carbanion attacks the strained epoxide ring to open the strained epoxide ring .The product of step 2 leads to generation  of   hex-3-yn-1-olate

Further on treating the product formed in step 2 with the dilute acid it leads to the formation of alcohol as the negative charge on oxygen can now be neutralised.

Kindly refer the mechanism for structure of compounds.

if you mean hydrogen and oxygen then water is the product
