# Different types of carbides [closed]

I am confused between different types of carbides such as

$\ce{CaC2}$, $\ce{Mg2C3}$, $\ce{Al4C3}$, $\ce{BaC2}$ or $\ce{BeC2}$.

And if they are different, why they are called carbides?

• Could you expand a little? Is there anything in particular associated with this set of carbides that is causing your confusion? Otherwise I have to admit I can't really see what you are asking - They are called carbides because they are a binary compound of carbon and a more electropositive element, but I feel that this is not really what you want to know – Ian Bush Mar 5 '17 at 12:59
• @IanBush actually I want to know whic carbide on hydrolysis produces which product – hey Mar 5 '17 at 15:01

• BaC2 and CaC2 on hydrolysis gives C2H2 Mg2C3 givesC3H4 Al4C3 and Be2C gives CH4 – kalyani Mar 5 '17 at 16:15

In chemistry, a carbide is a compound composed of carbon and a less electronegative element. Carbides can be generally classified by chemical bonding type as follows: (i) salt-like, (ii) covalent compounds, (iii) interstitial compounds, and (iv) "intermediate" transition metal carbides. Examples include calcium carbide ($\ce{CaC2}$), silicon carbide ($\ce{SiC}$), tungsten carbide ($\ce{WC}$) (often called simply carbide when referring to machine tooling), and cementite ($\ce{Fe3C}$), each used in key industrial applications. The naming of ionic carbides is not systematic.
