Решение
Геометрическими (или цис-транс) изомерами называют вещества, которые имеют одинаковый состав и порядок соединения атомов, но различаются пространственным расположением заместителей относительно плоскости двойной связи ($C=C$) или цикла. Для существования геометрических изомеров у алкенов необходимо, чтобы при каждом из двух атомов углерода, связанных двойной связью, находились два различных заместителя.
1)
В этой паре представлены два изомера 3-метилпентена-2. Молекулярная формула обоих веществ $C_6H_{12}$. У левого атома углерода при двойной связи находятся заместители: этильная группа ($-CH_2-CH_3$) и метильная группа ($-CH_3$). Они различны. У правого атома углерода при двойной связи находятся заместители: метильная группа ($-CH_3$) и атом водорода ($-H$). Они также различны. Так как условия для существования геометрической изомерии выполняются, а пространственное расположение заместителей относительно плоскости двойной связи различно, данные вещества являются геометрическими (цис- и транс-) изомерами.
Ответ: Вещества являются геометрическими изомерами.
2)
В этой паре дважды изображена молекула пропена ($CH_3-CH=CH_2$). У одного из атомов углерода при двойной связи (крайнего справа) находятся два одинаковых заместителя — два атома водорода ($-H$). Так как не выполняется условие наличия разных заместителей у каждого атома углерода при двойной связи, для пропена геометрическая изомерия невозможна. Представленные структуры являются одной и той же молекулой.
Ответ: Вещества не являются геометрическими изомерами.
3)
В этой паре дважды изображена молекула 2-метилбут-2-ена. У одного из атомов углерода при двойной связи находятся два одинаковых заместителя — две метильные группы ($-CH_3$). Условие для существования геометрической изомерии не выполняется. Представленные структуры являются одной и той же молекулой.
Ответ: Вещества не являются геометрическими изомерами.
4)
В этой паре изображены различные конформации молекулы н-пентана, которая является алканом. В алканах отсутствуют двойные связи, ограничивающие вращение. Различные изображения показывают разные конформации молекулы, которые легко переходят друг в друга за счет свободного вращения вокруг одинарных $C-C$ связей. Это не является геометрической изомерией.
Ответ: Вещества не являются геометрическими изомерами.
