An interstitial alloy contains carbon in one-fourth of the octahedral holes of a closest packed metal,M.What is the formula of this alloy? A) M₄C B) MC₄ C) MC D) M₂C E) MC₂

Question

Quizplus · Accepted Answer

In a closest packed structure, there is one octahedral hole per metal atom. If carbon occupies one-fourth of these holes, the ratio of metal to carbon is 4:1, giving the formula M₄C.
