Is br2 or nabr more soluble in ccl4
Which compound is most soluble in a polar solvent?
Ionic substances
Ionic substances are generally most soluble in polar solvents; the higher the lattice energy, the more polar the solvent must be to overcome the lattice energy and dissolve the substance. Because of its high polarity, water is the most common solvent for ionic compounds.
Is i2 soluble in CCl4?
The I2 molecules in iodine and the CCl4 molecules in carbon tetrachloride are both held together by weak intermolecular bonds. Similar intermolecular bonds can form between I2 and CCl4 molecules in a solution of I2 in CCL4. I2 therefore readily dissolves in CCl4.
Is CS2 soluble in CCl4?
There is a general rule: polar substances are soluble in polar solvents and insoluble in non-polar solvents, and non-polar substances are soluble in non-polar solvents and insoluble in polar solvents. … CS2 (ε = 2.6), CCl4 (ε = 2.2) and CHCl3 (ε = 4.8) are non-polar and that is why they are insoluble in water.
Does caf2 dissolve in CCl4?
a) Br2 (non-polar molecule); b) CH3OCH3 (ethers are less polar than alcohols); … d) I2 (non-polar molecule).
Why is br2 soluble in CCl4?
Notes: Bromine attaches a double bond (anti-addition) to the opposite sides. … The solvent is often mentioned in this reaction. Carbon tetrachloride is a popular solvent (CCl4).
What is most likely to dissolve in CCl4?
Iodine is more likely to dissolve in CCl4(ℓ). I2(s) and CCl4(ℓ) are both non- polar molecular compounds, whereas water is a polar molecular compound. There are no significant attractions between the non-polar I2 molecules and polar water molecules that would cause molecules of I2(s) to separate.
Why is br2 more soluble in CCl4 than in water?
If this is a question for school, then the answer you’re probably meant to give is this: because iodine and CCl4 are both non-polar, while water is polar. Non-polar substances dissolve better in non-polar solvents, while polar substances dissolve better in polar solvents.
Which is more soluble in CCl4 hexane or cacl2?
C-Carbon tetrachloride because it can form hydrogen bonds with hexane molecules. … G-Calcium chloride because it can form hydrogen bonds with hexane molecules. H-Calcium chloride because it can form ion-dipole interactions with hexane molecules, a bonding interaction much like dipole-dipole interactions but stronger.
Which is more soluble in water CCl4 or cacl2?
The answer is H. Calcium chloride because it can form ion-dipole interactions with water molecules, a bonding interaction much like dipole-dipole…
Is Br2 soluble?
Bromine is a dark reddish-brown fuming liquid with a pungent odor. Denser than water and soluble in water.
Is Br2 polar or nonpolar?
Br2 is nonpolar because both bromine atoms have identical electronegativity. This will result in an equal charge distribution.
Is Br2 soluble in hexane?
Halogens are more soluble in hexane than in water, so the halogen (Cl2, Br2, or I2) will move to the hexane layer.

Does c2h5oh dissolve in ccl4?
The ethanol dissolves in water but the carbon tetrachloride will not dissolve. And this is explained on the basis of hydrogen bonding present in the ethanol. But the carbon tetrachloride does not contain the hydrogen bonding.
Does Br2 dissociate in water?
During disinfection, hypobromous acid dissociates into bromide ions. These ions can be reactivated. Bromine reacts with other substances in the water to form bromine-containing substances.

Is Br2 an ionic compound?
Br2 is a homoatomic molecule, a molecule with same kind of atoms. So here the electronegativity of both the atoms is same so the shared pair is equally attracted by the two atoms. And it will be a covalent compound only. …
What charge is Br2?
Bromine is of group 17, meaning that it only requires to add one electron for it to have a full set of electrons in its outermost orbital, henceforth its valency is 1, so it’ll gain an electron to form bromide ion, having a charge of 1-.

What is the action of Br2 water?
In addition, bromine water is commonly used to test for the presence of an alkene which contains a double covalent bond, reacting with the bromine water, changing its color from an intense yellow to a colorless solution. Bromine water is also commonly used to check for the presence of an aldehyde group in compounds.
Can alkynes Decolourise bromine water?
Addition of bromine to an alkene or alkynes results in the formation of vicinal dibromide which decolourises bromine water.
