В условии нет вопроса, что найти?
Общая формула предельных спиртов СnH2n+2O
CnH2n+2O => CnH2n + H2O
CnH2n+2O + 3n/2O2 => nCO2 + (n+1)H2O
Исходя из условия задачи n=4. следовательно, формула спирта С4Н9ОН
Проверим правильность решения:
С4Н9ОН => C4H8 + H2O
C4H9OH + 6O2 => 4CO2 + 5H2O
Таким образом, объем бутена меньше объема углекислого газа в 4 раза, следовательно, решение верное.
Ответ: бутанол, бутен.
