Why glucose is not soluble in CCl4 but dissolve in water?

Answer 1

Well, darling, glucose is a sassy little molecule that loves to mingle with water because of its hydroxyl groups that can form hydrogen bonds with water molecules. On the other hand, CCl4 is like a closed-off club with no room for glucose to squeeze in because it's nonpolar and doesn't play nice with those hydroxyl groups. So, glucose struts its stuff in water but gets the cold shoulder from CCl4.

Answer 2

CCl4 is insoluble in water because it is non polar whereas water is polar. Polar substances are soluble in polar substances and nonpolar in nonpolar

Polarity is determined by the electro-negativity of the atoms in the molecule as well as the arrangement of the atoms.

in CCl4 the electrons are pulled towards the Cl and the arrangement ensures that the outside of the molecule is evenly negative while the inside is positive

in H2O, the electrons are pulled towards the Oxygen but the arrangement of the molecules means that one side of the molecule is partially negative while the other side is partially positive

P.S. look up the structures of both molecules and this will become more clear

Answer 3

Glucose is a polar molecule due to its many hydroxyl (-OH) groups, allowing it to form hydrogen bonds with water molecules, making it soluble in water. Carbon tetrachloride (CCl4) is a nonpolar solvent, lacking the ability to form hydrogen bonds with glucose, leading to poor solubility.

Answer 4

Carbon tetrachloride is more dense than water and doesn't float.

Answer 5

Acetylene is not a polar compound.

Answer 6

becausa it is soluble in water
