Correct order of Rotational energy barrier will be

(I) (II) (III)

Answer:

Solution:

More single bond character less energy barrier for rotation.

(I) $CH_{3} - CH = CH - CH_{3}$ Single bond character is produced due to hyperconjugation.

(II) Due to resonance more single bond character is produced.

(III) Most single bond character is produced due to $+ R$ & $- R$ of – $OCH_{3}$ and – $NO_{2}$ respectively .
