The correct order of the stability of the following compounds based on hyperconjugation is
Options
- AIV > III > II > I
- BIV > II > I > III
- CIV > II > III > I
- DIV > I > III > II
Correct answer
A. IV > III > II > I
Step-by-step solution
Hyperconjugation increases the stability of alkene which does not have any other resonance effect. And hyperconjugation effect depends on the number of alpha hydrogen around the alkene. More the number of alpha hydrogen atoms more stable the alkene will be. So, stability order will be IV > III > II > I .
