Question- Briefly explain in your own words why the 3dz2 and 3dx22y2 orbitals should be degenerate in an octahedral field even though they are of quite different shapes.
If possible just a brief explanation how you got the answer?
Imagine that a chemist has cyclohexanone, triphenylphosphine, butyllithium, and 2-bromobutane. Draw the organic product resulting from using these chemicals in the Wittig reaction.
The blank solution used to calibrate the spectrophotometer s 10.0mL of 0.2 M Fe(NO3)3 diluted to 25.0 mL with0.1 M HNO3. Why is this solution preferred to simplyusing de-ionized water for the calibration
