Correct order of Rotational energy barrier will be

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) $CH_{3} - CH = CH - . O Me$ Due to resonance more single bond character is produced.

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