Solution
The statement is true.
Sodium does not form carbide, Na2C2 with carbon but Na2C2 can be formed when sodium reacts with acetylene.
Sodium acetylide (Na2C2) is formed when sodium reacts with acetylene.
CH≡CH+2Na→Na−C≡Na
(sodium acetylide)
Among alkali metals, only lithium forms a carbide (Li2C2) similar to that of calcium. The other alkali metals do not form stable carbides, although they do react with the graphite form of carbon to give intercalation compounds and di-substituted acetylides.
