Count the linkage isomers of K₄[Fe(CN)₄(NO₂)(SCN)], where each CN⁻ can bond through C or N, NO₂⁻ through N or O and SCN⁻ through S or N. Count the four cyanides only by how many are N-bonded.

Question

TestHub · Accepted Answer

The four cyanides give 5 patterns (0 to 4 N-bonded). NO₂⁻ gives 2 forms and SCN⁻ gives 2 forms. Total = 5 × 2 × 2 = 20.
