The Deep Dive

Спочатку розглянемо молекулярні маси кожної з речовин. Пентан (С5Н12) має молекулярну масу приблизно 72 г/моль, гексан (С6Н14) – близько 86 г/моль, пентин (С5Н10) – приблизно 70 г/моль, а гептин (С7Н14) – близько 100 г/моль. Зважаючи на це, порядок збільшення молекулярної маси буде: пентан (Г), пентин (Б), гексан (В), гептин (А). Згідно з наведеною інформацією, правильний порядок: Г > Б > В > А.
