Explain why ethanol and water are miscible yet tetrachloride and water are immiscible.​

CCl4 can neither form H-bonds with water molecules nor can it break H-bonds in water molecules. Therefore, it is insoluble in water. Ethanol is a polar compound and can form H-bonds with water, which is a polar solvent. Therefore,it is miscible with water in all proportions

Explanation:

FIRSTLY WATER MOLECULES CONTAIN ONE OXYGEN AND TWO HYDROGEN(H2O) .HENCE IN THIS STRUCTURE THE BOND BETWEEN OXYGEN AND HYDROGEN IS COVALENT AND POLARIZABLE .HENCE OXYGEN ATOM ATTRACTS ELECTRONS MORE STRONGLY TOWARDS INWARDS AS COMPARE TO 2 HYDROGEN ATOMS. DUE TO WHICH OXYGEN ATOM GET SLIGHTLY NEGATIVE CHARGE AND 2 HYDROGEN OCCUPY SLIGHTLY POSITIVE CHARGE THAT MAKE WATER A POLAR MOLECULE. :NOW IN ETHANOL(CH3CH2OH),ETHANOL MOLECULE IS FORMED BY 2 CARBON ATOM JOINED BY SINGLE BOND WHICH IS NOT POLAR.IN β CARBON OF ETANOL CARBON IS BONDED TO 3 HYDROGEN ATOMS WHICH MAKES IT NON POLAR DUE TO SYMMETRY BUT α CARBON HAS 2 HYDROGEN AND 1 OH- ION (SAME AS IN THE CASE OF WATER MOLECULE) SO THIS CARBON ATOM BECAMES POLAR AND HENCE ETHANOL MOLECULES BECAMES POLAR. NOW WE KNOW THAT SAME CHARGE REPEL EACH OTHER AND UNLIKE CHARGES ATTRACTS EACH OTHER SO THE SLIGHTHLY POSITIVE CHARGE OF WATER MOLECULE MAKES A BOND WITH THE.
