What is the oxidation state of carbon in CaC_2 and K_2C_2O_4 respectively?

Question

Accepted Answer

Correct answer: B. (b): For CaC_2 ,+2+2x=0 ∴ 2x=-2 or x=-1 For K_2C_2O_4 ,2 (+1 )+2 (x )+4 (-2 )=0 ∴2+2x-8=0 or 2x=6 or x=+3 The oxidation states of carbon in CaC_2 and K_2C_2O_4 are -1 and +3 respectively.
