Question

scrie succesiunea ecuatiilor reactiilor ce permite urmatoarele transformari:
a)etanol---etan-1,2-diol;
b)butan-2-ol---butan-2,3-diol

Answer 1

CH3CH2OH---CH2=CH2+H2O
CH2=CH2+Cl2=CH2Cl-CH2Cl
CH2Cl-CH2Cl+2H2O=CH2OH-CH2OH
CH3-CHOH-CH2-CH3----CH3-CH=CH-CH3
CH3-CH=CH-CH3+Cl2  =  CH3-CHCl-CHCl-CH3
CH3-CHCl-CHCl-CH3+2H2O=  CH3-CHOH-CHOH-CH3
