Identify the correct stability order of following alkenes. I) ( CH ₃ )₂ C = C ( CH ₃ )₂ II) ( CH ₃ )₂ C = CH ₂ III) ( CH ₃ )₂ C = CHCH ₃
Options
- AIII II I
- BI III II
- CII I III
- DI II III
Correct answer
B. I III II
Step-by-step solution
The alkene that has greater number of alkyl groups attached to doubly bonded carbon atoms is more stable than other alkenes. Order of stability of alkenes with respect to Saytzeff rule is: aligned & ( CH ₃ )₂ C = C ( CH ₃ )₂ ( CH ₃ )₂ C = CH ( CH ₃ ) & ( CH ₃ )₂ C = CH ₂ aligned
