б) химическими свойства.
Поясняю: оба представляют из себя жир, который невозможно по физическим свойствам определить. Триолеатглицерин представляет собой сложный эфир, состоящий из глицерина и олеиновой кислоты, которая как раз непредельная и легко можно её выявить с помощью качественных химических реакций, например с бромной водой (обесцвечивание). Тристеоратглицерин представляет собой сложный эфир, состоящий из глицерина и стеариновой кислоты, которая предельная и нет на её качественных реакций.
