Which among the following alkenes is most stable?

Options

AR ₂ C = CH ₂
BH ₂ C = CH ₂
CRCH = CHR
DR ₂ C = CR ₂

Correct answer

D. R ₂ C = CR ₂

Step-by-step solution

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