Which from following alkyl substituted alkenes is most stable?

  • Correct answer
    A
    $\mathrm{R}_2 \mathrm{C}=\mathrm{CR}_2$
  • B
    $\mathrm{R}_2 \mathrm{C}=\mathrm{CHR}$
  • C
    $\mathrm{R}_2 \mathrm{C}=\dot{\mathrm{CH}}_2$
  • D
    $\mathrm{RCH}=\mathrm{CH}_2$

Solution

Greater is the number of alkyl groups attached to the doubly bonded carbon atoms, greater is the stability of alkene. $\therefore \quad \mathrm{R}_2 \mathrm{C}=\mathrm{CR}_2$ is the most stable alkene.

Hence, the correct answer is option: 'A'.
