has the following characteristics:

View answer and explanation

Correct option: D

All of the above

Option D is correct because Magnesium carbide (

\mathrm{M}{\mathrm{g}_2}{\mathrm{C}_3}

) contains

\mathrm{M}{\mathrm{g}^{2 + }}\;and\;\mathrm{C}_3^{4 - }

ions, is called magnesium allylide, and produces propyne upon hydrolysis.
