Question

The order of stability of the alkenes R 2 C = CR 2 , R 2 C = CHR , R 2 C = CH 2 , RCH = CHR , RCH = CH 2 I II III IV V ( R = − CH 3 ), I > II > III > IV > V, I = II > III > IV > V, II > I > IV > III > V, V > IV > III > II > I

MARKS App · Accepted Answer

More substituted alkenes are more stable (more hypercnjugation) and alkyl groups on two different carbon atoms makes it more stable I > II > III > IV > V
