Options

AH ₂ O
BNH ₃
CS ²⁻
DNCS ^-

Correct answer

B. NH ₃

Step-by-step solution

According to the spectrochemical series, the arrangement of ligands in the increasing order of their crystal field splitting energy (CFSE) values is: I^- From the given options, the order of field strength is S²⁻ Thus, NH ₃ has the highest field strength. Answer: NH ₃
