`Al_4C_3,Mg_2C_3` and `CaC_2` are hydrolyzed separately. The hydrocarbons formed are _____ respectively.

Options

A. acetylene, methane, methylecetylene
B. methylecetylene, methane, acetylene
C. methanem, methylacetylene, acetylene
D. methylacetylene, acetylene, methane

Answer

C

Explanation

`(Al^(3+))_4(C^(4-))_3overset(overset(sigma+)(H)-overset(sigma-)(OH))toCH_4`
`(Mg^(2))_2(C^(3-)-overline(C)-=C)toCH_3C-=CH`
`Ca^(2+)(overline(C)-=overline(C))toCH-=CH`
