1. (Sửa: $E+2NaOH\to CH_4$)

   $C_3H_6$: xiclopropan 

   $A: CH_2Cl-CH_2-CH_2Cl$

   $B: CH_2OH-CH_2-CH_2OH$

   $C: OHC-CH_2-CHO$

   $D: HOOC-CH_2-COOH$

   $E: NaOOC-CH_2-COONa$

   PTHH:

   $C_3H_6+Cl_2\to ClCH_2-CH_2-CH_2Cl$

   $ClCH_2-CH_2-CH_2Cl+2NaOH\xrightarrow{{t^o}} HOCH_2-CH_2-CH_2OH$

   $HOCH_2-CH_2-CH_2OH+2CuO\xrightarrow{{t^o}} OHCCH_2CHO+2Cu+2H_2O$

   $OHC-CH_2-CHO+2Br_2+2H_2O\to HOOC-CH_2-COOH+4HBr$

   $HOOC-CH_2-COOH+2NaOH\to NaOOCCH_2COONa+2H_2O$

   $NaOOCCH_2COONa+2NaOH\xrightarrow{{CaO, t^o}} 2Na_2CO_3+CH_4$
