1,CH2=CH-COOCH3 +H2O—-> 2, CH3-COO-CH=CH-CH3 +NaOH—-> 3, C2H5COO- C(CH3)=CH2+NaOH—-> Mn giúp mình với ạ :(((
2 câu trả lời
Đáp án + giải thích các bước giải:
1. $CH_2=CHCOOCH_3+H_2O\buildrel{{H_2SO_4;t^o}}\over\rightleftharpoons CH_2=CHCOOH+CH_3OH$
2. `CH_3COOCH=CHCH_3+NaOH \to CH_3COONa+C_2H_5CHO`
3. `C_2H_5COOC(CH_3)=CH_2+NaOH \to C_2H_5COONa+CH_3COCH_3`
1)
$CH_2=CHCOOCH_3+H_2O\buildrel{{H^+,t^o}}\over\rightleftharpoons CH_2=CHCOOH+CH_3OH$
2)
$CH_3COOCH=CHCH_3+NaOH\xrightarrow{{t^o}} CH_3COONa+ CH_3-CH_2-CHO$
3)
$C_2H_5COOC(CH_3)=CH_2+NaOH\xrightarrow{{t^o}} C_2H_5COONa+CH_3COCH_3$
