Có 2 đồng phân là : C nối 3 CH nối 2 CH2

CH2 nối 2 C nối 2 CH2

A

a, 2C2H5OH + 2Na -> 2C2H5ONa +H2

b, nH2 = 2/2 =1 (mol)

Từ pthh => nC2H5OH = 2nH2 = 2 (mol)

=> x= 46×2 = 92(g)

c, từ pthh => nNa = 2nH2 = 2 (mol)

=> y=23×2 = 46 (g)

d, từ pthh => nC2H5ONa = 2nH2=2(mol)

=> mC2H5ONa = 68×2 = 136 (g)
