11 1-diisopropylethene < (Z)-1 2-diisopropylethene < (E)-1 2-diisopropyletheneThe compounds are listed in order of increasing stability. Why?2Also what does the C=C-C bond angle have do to with stability?And the order of increasing C=C-C bond angle is 1 1 < E < Zwhy is the order different from question 1?
