A

`C^(4-)` ions

B

`C_(2)^(2-)` ions

C

`C_(3)^(2-)` ions

D

`C_(3)^(4-)` ions

Text Solution

Verified by Experts

The correct Answer is:
D
Allylides gives `1`-propyne on hydrolysis with water, e.g.
`Mg_(2)C_(3)+4H_(2)Oto2Mg(OH)_(2)+CH_(3)^(-)C CH`
Such compounds contain `C_(3)^(4-)[:underset(..)ddotC-C-=C:]^(4-)` ions.
