Which from following alkyl substituted alkenes is most stable?
- 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 \(\mathrm{RCH}=\mathrm{CH}_2\)
Answer & Solution
Correct Answer
(A) \(\mathrm{R}_2 \mathrm{C}=\mathrm{CR}_2\)
Step-by-step Solution
Detailed explanation
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.
\(\therefore \quad \mathrm{R}_2 \mathrm{C}=\mathrm{CR}_2\) is the most stable alkene.
