Question

помогите,пожалуйста.

Answer 1

a)

1)C2H5OH+HBr = C2H5Br+H2O

2)C2H5Br + KOH(спирт) = CH2=CH2

3)C6H5C2H5 + Br2 = C6H5C2H4Br + HBr

4)C6H5C2H4Br + KOH = C6H5C2H4OH + KBr

б)

1)HCOH + H2 = CH3OH

2)2CH3OH + 2Na = 2CH3ONa + H2

3)CH3ONa + HCl = СН3ОН + NaCl

4)5СН3ОН + 4KMnO4 + 6H2SO4 = 5HCOOH + 4MnSO4 +2K2SO4 + 11H2O
