Vedclass · Answer

(A) The stability of alkenes is determined by the number of hyperconjugative structures (alpha-hydrogens) and steric factors. $I$: Tetrasubstituted alkene, $12 \ \alpha-H$, most stable. $III$: Trisubstituted alkene, $9 \ \alpha-H$. $II$: Disubstituted trans-alkene, $6 \ \alpha-H$, more stable than cis due to less steric hindrance. $IV$: Disubstituted cis-alkene, $6 \ \alpha-H$, less stable than trans. Thus, the decreasing order of stability is $I > III > II > IV$.

Arrange the following alkenes in decreasing order of stability. Choose the correct answer from the options given below:
