The correct sequence of electronic configuration is:
- 4p 3s 4d 5p 6s 4f 5d
- 4p 4s 4d 5p 5s 4f 5d
- 4p 5s 4d 5p 6s 4f 5d
- 4p 4s 4d 5d 5s 5f 6d
Which of the following involve the same steps
- SN1 and SN2
- E1 and E2
- E2 and SN1
- E1 and SN1
SN1 reactions mostly result In partial racemization. In partial racemization there is
- Retention only
- Inversion only
- Equal inversion and retention
- More inversion than retention
Greater number of alky groups on substrate favors
- Substitution reaction
- Oxidation reaction
- Elimination reaction
- Free radical reaction
