Помогите решить цепочку 1) CH3-C≡СAg- (HCI) ->X1- (избHBr) ->X2->X1- (Hg) ->X3->пропанол-2

1) CH3-C=-CAg+HCl=CH3-C=-CH+AgClCH3-C=-CH+2HBr=CH3-CBr2-CH3CH3-CBr2-CH3+2KOH=CH3-C=-CH+2KBr+2H2OCH3-C=-CH+HOH (Hg2+)=CH3-CO-CH3CH3-CO-CH3+H2=CH3-CHOH-CH3. 2) CH3-COH+2KMnO4+3KOH=CH3-COOK+2K2MnO4+2H2OCH3-COOK+H2SO4=CH3-COOH+KHSO4CH3-COOH+CH3OH=CH3-CO-O-CH3+H2O2CH3-CO-O-CH3+Ca (OH) 2=2 (CH3COO) 2Ca+2CH3OH (CH3COO) 2Ca (t)=CH3-CO-CH3+CaCO3…
