Nacl is an ionic solid. the na+ and cl− ions in nacl are bonded through an electrostatic force of attraction commonly known as t

he ionic bond. water is a polar solvent. the oxygen atom, being more electronegative, attracts the electron cloud toward itself. as the electron cloud is pulled by the oxygen atom, it carries a partial negative charge, and the hydrogen atoms carry a partial positive charge. this partial separation of charges in the water molecule makes it polar. which intermolecular forces contribute to the dissolution of nacl in water?

NaCl is the poster-compound for ionic bonding. The bonds in NaCl have approximately 70% ionic character, making the bonds highly polar. It's an exaggeration to say that there are real ions in NaCl with +1 and -1 charges, but the real charges of Na and Cl are certainly close to the expected +1 and -1, correspondingly. Since NaCl is as a network of extremely charged particles, and not separate molecules, NaCl does not display intermolecular forces. 

Water molecules conversely do display London dispersion forces, Keesom forces and hydrogen bonding. 

The polar water molecules are involved to the polarized Na and Cl atoms. This is what permits NaCl(s) to dissolve and ionize in water. Consequently, the kind of attraction accountable for the ionization of NaCl is ion-dipole attraction.

The ion - dipole attractions between the Na+ and the polar water molecule and the ion - dipole attractions between the Cl- and the polar water molecule contribute to the dissolution of sodium chloride in water.

Further Explanation:

Sodium chloride is an ionic compound. The electrostatic attraction between its positive charged ions (Na+) and negatively charged ions (Cl-) holds the crystal lattice together.

Water is a polar molecule. Polar molecules have a net dipole moment due to the differences in electronegativity of the atoms in the molecule and the geometry of the molecule as well. Since oxygen is more electronegative than hydrogen, it pulls the shared electrons towards itself. The part of the molecule where oxygen is, gains a partial negative charge, since the shared electrons spend more time in this region than near hydrogen. The hydrogen side of the molecule, then becomes mostly electron-deficient giving it a partial positive charge.

In the dissolution of sodium chloride in water, the ion - ion attractions of the salt is weakened as it absorbs heat. Then, polar water molecules start to surround individual Na+ or Cl- ions by orienting themselves accordingly: the partial negative side of water are attracted to the Na+ and the H side of the water molecule is attracted to the Cl- ions. With enough water molecules surrounding the each ion, the ion - dipole attractions formed overcome the ion - ion attraction of the salt.

Answer:

C. 1, 4–dimethyl–1–cyclohexene

D. 4, 6–dichloro–1–heptene

Explanation:

C. Determination of the name of the compound.

To name the compound given above we must observe the following:

1. Determine the functional group of the compound. In this case, the functional group is the double bond (–C=C–).

2. Determine the parent name by counting the number of carbon that makes up the ring. In this case, 6 carbon makes up the ring. Hence the parent name is cyclohexene.

3. Identify the substituent group attached to the compound. In this case, two methyl group i.e –CH₃ are attached.

4. Locate the position of the substituent group attached by giving the functional group the lowest possible count. In this case, the functional group is at carbon 1, the first methyl group is at carbon 1 and the 2nd methyl group is at carbon 4.

5. Combine the above to obtain the name. Thus, the name of the compound is:

1, 4–dimethyl–1–cyclohexene.

D. Determination of the name of the compound.

To name the compound given above we must observe the following:

1. Determine the functional group of the compound. In this case, the functional group is the double bond (–C=C–).

2. Determine the parent name by counting the number of carbon that makes up the chain. In this case, 7 carbons makes up the chain. Hence, the parent name of the compound is heptene.

3. Identify the substituent group attached to the compound. In this case, two chlorine (Chloro) i.e –Cl are attached.

4. Locate the position of the substituent group attached by giving the functional group the lowest possible count. In this case, the functional group is at carbon 1, the first chlorine is at carbon 4 and the 2nd is at carbon 6.

5. Combine the above to obtain the name. Thus, the name of the compound is:

4, 6–dichloro–1–heptene
