Bài 2:
a, - Dẫn từng khí qua bình đựng Br2.
+ Br2 nhạt màu dần: C2H4
PT: \(C_2H_4+Br_2\rightarrow C_2H_4Br_2\)
+ Không hiện tượng: C2H6.
b, A: C2H5OH
B: CH3CH2CH2OH, CH3CH(OH)CH3
C: CH3CH2CH2CH2OH, CH3CH(OH)CH2CH3, CH3C(CH3)(OH)CH3, CH3CH(CH3)CH2OH
c, \(CH_2=CH_2+Br_2\rightarrow CH_2Br-CH_2Br\)
\(C_3H_8+5O_2\underrightarrow{t^o}3CO_2+4H_2O\)
\(C_2H_4+3O_2\underrightarrow{t^o}2CO_2+2H_2O\)
\(nCH_2=CH_2\underrightarrow{^{t^o,xt,p}}\left(-CH_2-CH_2-\right)_n\)
\(C_2H_5OH+3O_2\underrightarrow{t^o}2CO_2+3H_2O\)
\(C_2H_5OH+Na\rightarrow C_2H_5ONa+\dfrac{1}{2}H_2\)
\(C_6H_{12}O_6\underrightarrow{^{enzyme}}2C_2H_5OH+2CO_2\)
\(2C_xH_y+\dfrac{4x+y}{2}O_2\underrightarrow{t^o}2xCO_2+yH_2O\)
\(2C_nH_{2n}+3n_{O_2}\underrightarrow{t^o}2nCO_2+2nH_2O\)
