Answer:
The more polar the molecules, the stronger the force. The more hydrogen in the molecule, the stronger the force.

B. HCl
C. CF4
D. CuSO4
will be insoluble in water.
Further Explanation:
The bond formed due to electrostatic forces is an ionic bond. The compounds formed by the ions of the respective species are called ionic compounds. One of the species loses electrons and gets converted into cation while the other one accepts electrons and forms anion.
Covalent compound:
The bond that is formed by the mutual sharing of electrons between the bonded atoms is called a covalent bond. It is also known as a molecular bond. Covalent compounds or molecular compounds are those compounds which are formed by the electron sharing between two or more non-metals.
Solubility is the property of any substance that makes it soluble in other substances. It is governed by the principle “like dissolves like”.
A. NaCl is an ionic compound so it dissociates into its constituent ions on dissolving in water. Water is a polar molecule and therefore NaCl is soluble in water.
B. HCl is a polar covalent compound and water is also a polar compound so HCl is soluble in water in accordance with the principle “like dissolves like”.
C. is a non-polar compound while water is a polar compound. So is insoluble in water because of different nature of both substances.
D. is an ionic compound so it dissociates into and ions on dissolving in water. Water is a polar molecule and therefore is soluble in water.

Chapter: Ionic and covalent compounds
Keywords: ionic compound, covalent compound, solubility, NaCl, HCl, CuSO4, CF4, soluble, insoluble, water, like dissolves like.
Among the compounds NaCl, HCl, CuSO4, and CF4, the latter, CF4, is predicted to be insoluble in water due to its nonpolar nature.
The insolubility of a compound in water depends on its polarity. Nonpolar compounds do not dissolve in water, a polar solvent. The compounds NaCl, HCl, and CuSO4 are all polar ionic compounds and, therefore, soluble in water, since 'like dissolves like'. However, the compound CF4 is a nonpolar molecule and hence predicted to be insoluble in water.

Explanation:
First, calculate the moles of using ideal gas equation as follows.
PV = nRT
or, n =
= (as 1 bar = 1 atm (approx))
= 0.183 mol
As, Density =
Hence, mass of water will be as follows.
Density =
0.998 g/ml =
mass = 3.25 g
Similarly, calculate the moles of water as follows.
No. of moles =
=
= 0.180 mol
Moles of hydrogen = = 0.36 mol
Now, mass of carbon will be as follows.
No. of moles =
0.183 mol =
= 2.19 g
Therefore, mass of oxygen will be as follows.
Mass of O = mass of sample - (mass of C + mass of H)
= 3.50 g - (2.19 g + 0.36 g)
= 0.95 g
Therefore, moles of oxygen will be as follows.
No. of moles =
=
= 0.059 mol
Now, diving number of moles of each element of the compound by smallest no. of moles as follows.
C H O
No. of moles: 0.183 0.36 0.059
On dividing: 3.1 6.1 1
Therefore, empirical formula of the given compound is .
Thus, we can conclude that empirical formula of the given compound is .
