Wh do you think is the better choice? Give reasons to support your choice. Section 4: 4. Chloromethane, CH3CI has many uses, one of which is an extractant for oils. Chemists often use the phrase "like dissolves like" to summarize the observation that polar solvents prefer to interact with polar molecules, and nonpolar solvents prefer to interact with nonpolar molecules. Use this fact to explain why Chloromethane, CH3CI, is a good extractant for oils. Oils are nonpolar substances containing carbon and hydrogen atoms.

Formal Charges

Formal charges have an important role in organic chemistry since this concept helps us to know whether an atom in a molecule is neutral/bears a positive or negative charge. Even if some molecules are neutral, the atoms within that molecule need not be neutral atoms.

Polarity Of Water

In simple chemical terms, polarity refers to the separation of charges in a chemical species leading into formation of two polar ends which are positively charged end and negatively charged end. Polarity in any molecule occurs due to the differences in the electronegativities of the bonded atoms. Water, as we all know has two hydrogen atoms bonded to an oxygen atom. As oxygen is more electronegative than hydrogen thus, there exists polarity in the bonds which is why water is known as a polar solvent. 

Valence Bond Theory Vbt

Valence bond theory (VBT) in simple terms explains how individual atomic orbitals with an unpaired electron each, come close to each other and overlap to form a molecular orbital giving a covalent bond. It gives a quantum mechanical approach to the formation of covalent bonds with the help of wavefunctions using attractive and repulsive energies when two atoms are brought from infinity to their internuclear distance.
