Ответ:Следует указать молекулярную формулу алкена, необхидно знати масляную фракцию галогена (брома) в результате реакции алкена с гидроген бромом.

По значимой масову частку галогену як x.

С молекулярной формулой алкена, которая наиболее значима как CxHyBrz, может быть обнаружена, как масса галогена (Br), становящаяся молекулой всего галогена у сполуці.

Отже, масова частка галогена (x) может быть бути видена как:

x = (маса Br) / (маса CxHyBrz) * 100%

Знаю, что що масова частка галогену становит 52,98%, органо записати:

0,5298 = (маса Br) / (маса CxHyBrz) * 100%

За допо- могою этого вида виразу я не могу точно определить молекулярную формулу алкена, опробовать не зна- чимо значення маси галогена (Br) или маси CxHyBrz.

Тому, без дополнительной информации о масу галогену или масу CxHyBrz, мы не рекомендуем указывать точную молекулярную формулу алкену.
