The product obtained as a result of a reaction of nitrogen with CaC2 is:
(a) CaCN (b) CaCN3 (c) Ca2CN (d) CaCN2
(d) When calcium carbide (CaC2) reacts with nitrogen (N2) under high temperature, it forms calcium cyanamide which is also called nitrolim.
CaC2 + N2 CaCN2 + C
Hence, option (d) should be CaCN2 instead of Ca(CN)2
