CₓHy₋₁ -OH <=> CₓHyO, μ=12x+y+16
raportam la C - 9/15=12x/12x+y+16
raportam la O - 4/15=16/12x+y+16 => μ=12x+y+16=60 (g/mol)
=> 9/15=12x/60 => x=3
12x+y+16=60 => 36+y+16=60 => y=8
=> F.ch. M C₃H₈O , NE= 6+2-8/2=0 (compus saturat)
alcool monohidroxilic primar - CH₃-CH₂-CH₂-OH, alcool propilic, 1-propanol
a) CH₂=CH-CH₃ + H₂O ->> CH₃-CH(OH)-CH₃ - alcool izopropilic, conform regulii lui Markovnikov => F
b) (μ=)60 g...... 36 g C...... 8 g H.... 16 g O
100%........ 60%C.........13,33%H....26,667%O (A)
c) 3+8+1=12 atomi
d) e izomer de pozitie cu alcoolul izopropilic ( ai formula mai sus)
e) NE=0.. compus saturat
