Question

un alcool monohidroxilic, saturat, secundar (A) are raportul masic de combinare C:H = 4,8. determinati formula de structura a alcoolului (A).

Answer 1

alcool monohidroxilic, saturat => C_{n}H_{2n+1}O => $\frac{C}{H} = \frac{12n}{2n+2}= 4,8 =\ \textgreater \ 12n= 9,6 n + 9,6 =\ \textgreater \ n(12-9,6)=9,6 =\ \textgreater \ n=4$

=> C_{4}H_{8}O
