prin hidratare
CH3-C(CH3)=CH2 +HOH==> CH3-(HO)C(CH3)-CH3 2metil 2propanol
CH3-C(CH3)=CH-CH2-CH3+HOH--> CH3-(HO)C(CH3)-CH2-CH2-CH3
2metil 2 pentanol
CH2=C(C2H5)-CH2-CH3+HOH--> CH3-(HO)C(C2H5)-CH2-CH3
2 etil 2 butanol
In acesti alcooli, OH e legat de C tertiar si nu se oxideaza
izomerii pot fi de pozitie si de catena:
de pozitie CH3-CH(CH3)-CH2OH 2 metil propanol
de catena CH3-CH2-CH2-CH2OH butanol ETC.........
