The correct stability order of alkyl substituted alkenes is

Options

  1. AR ₂ C = CHR R ₂ C = CH ₂ R ₂ C = CR ₂
  2. BR ₂ C = CR ₂ R ₂ C = CHR R ₂ C = CH ₂
  3. CR ₂ C = CH ₂ R ₂ C = CR ₂ R ₂ C = CHR
  4. DR ₂ C = CR ₂ R ₂ C = CH ₂ R ₂ C = CHR

Correct answer

B. R ₂ C = CR ₂ R ₂ C = CHR R ₂ C = CH ₂

Step-by-step solution

Order of stability of alkyl substituted alkenes: R ₂ C = CR ₂ R ₂ C = CHR R ₂ C = CH ₂ Greater is the number of alkyl groups attached to the doubly bonded carbon atoms, greater is the stability of alkene.
