The correct answer is statement 3, the difference in electronegativity between carbon and oxygen is greater than that between fluorine and oxygen. The most polar bond is the one with the highest difference in electronegativity values between two atoms. In this case, the C-O bond.

Answer: (3) The difference in electronegativity between carbon and oxygen is greater than that between fluorine and oxygen.

Explanation: Polarity of a molecule is due to the difference in electronegativity of the atoms. More is the electronegativity difference, more is the polarity.

Electronegativity of carbon = 2.5

Electronegativity of oxygen = 3.5

Electronegativity of fluorine = 4.0

Thus the difference in electronegativity of carbon and oxygen is=(3.5-2.5)= 1.0

Thus the difference in electronegativity of fluorine and oxygen is=(4.0-3.5)= 0.5.

Thus C-O bond is more polar than F-O bond.

What is the relationship between the concentration of particles in a solution and the solution’s vapor pressure? As solute conce

kap26 [50]

Answer:

As solute concentration increases, vapor pressure decreases.

Step-by-step explanation:

As solute concentration increases, the number of solute particles at the surface of the solution increases, so the number of solvent particles at the surface decreases.

Since there are fewer solvent particles available to evaporate from the surface, the vapour pressure decreases.

C. and D. are wrong. The vapour pressure depends only on the number of particles. It does not depend on the nature of the particles.

Explain the three states of matter on the basis of characteristics of particles/ molecules of matter.

Xelga [282]

Answer :

Explanation For The Three States OF Matter On the Basis OF Characteristics Of Particles / Molecules OF Matter.

<h3>Solid: </h3>

In solids the molecules are closely packed . There is a strong force of attraction between the molecules and the space between them is very small (almost negligible). The molecules are , therefore, not free to move . They merely vibrate their mean positions . This makes solids hard and difficult to compress , giving them a fixed shape and size.

<h3>Liquid : </h3>

In the case of liquids , the molecules are not closely packed. They do not attract each other as strongly as the molecules of solids. Thus, the intermolecular spaces are larger and the molecules are able to move about more freely . This makes liquid flow and take the shape of the container into which it is poured. Thus, liquids have a fixed volume but no definite shape of their own .

In the case of gases, the molecules hardly attract each other. They lie far a part from each other and the intermolecular spaces are, therefore, very large. . The intermolecular force of attraction is so weak that the molecules have great freedom of movement . As a result , gases have neither a fixed shapenor a fixed volume . They completely full up spacw available to them. They can be easily compressed as well, thus decreasing the gaps between their molecules .
