Question

Which of the following is correct order of crystal field splitting?

• A. $C$-donor $>N$-donor $>O$-donor
• B. $N$-donor $>O$-donor $>C$-donor
• C. $C$-donor $>O$-donor $>N$-donor
• D. $O$-donor $>N$-donor $>C$-donor

Answer 1

The correct option is A $C$-donor $>N$-donor $>O$-donor

Due to less electronegativity of carbon, carbon donor can donate more compared to Nitrogen donor and as nitrogen is less electronegative compared to oxygen donor.

It donates more compared to oxygen donor.

Thus, correct order is :

$\Rightarrow$ C- Donor> N-donor>O-donor

Therefore, the option is A.
