4. The boiling points of the four compounds: ethane (CH3CH3), ethanol (C2H$OH), dimethyl ether (CH3OCH;) and ethylene glycol (CH2OH-CH2OH) follow the order: 1). ethanol > ethane > dimethyl ether> ethylene glycol 2). ethylene glycol > ethanol > dimethyl ether > ethane 3). ethane > dimethyl ether > ethanol > ethylene glycol 4). ethylene glycol > dimethyl ether > ethanol > ethane 5. The process of fractional distillation can be used for the liquids having sufficient: 1). differences in their boiling points 2). differences in their melting points 3). differences in their solubility 4). differences in their viscosity 6. Three liquids A, B and C boil at 353 K, 403 K and 503 K, the vapor pressures of the three liquids at room temperature would follow the order: 1). A>B >C 2). В > А> C 3). A > С> В 4). C>A>B
