The number of mole of lithium, Li needed for the reaction is 3.2 moles (Option D)

<h3>Balanced equation </h3>

4Li + N₂(g) → 2Li₂N

From the balanced equation above,

2 moles of Li₂N were obtained from 4 moles of Li

<h3>How to determine the mole of lithium needed </h3>

From the balanced equation above,

2 moles of Li₂N were obtained from 4 moles of Li

Therefore,

1.6 moles of Li₂N will be obtained from = (1.6 × 4) / 2 = 3.2 moles of Li

Thus, 3.2 moles of Li are needed for the reaction

Answer:

See explanation and image attached

Explanation:

This reaction is known as mercuric ion catalyzed hydration of alkynes.

The first step in the reaction is attack of the mercuric ion on the carbon-carbon triple bond, a bridged intermediate is formed. This bridged intermediate is attacked by water molecule to give an organomercury enol. This undergoes keto-enol tautomerism, proton transfer to the keto group yields an oxonium ion, loss of the mercuric ion now gives equilibrium keto and enol forms of the compound. The keto form is favoured over the enol form.
