DCM's volatility and ability to dissolve a wide range of organic compounds makes it a useful solvent for many chemical processes. [12] In the food industry, it is used to decaffeinate coffee and tea as well as to prepare extracts of hops and other flavourings.
Polar molecules must contain one or more polar bonds due to a difference in electronegativity between the bonded atoms. Molecules containing polar bonds have no molecular polarity if the bond dipoles cancel each other out by symmetry. Polar molecules interact through dipole-dipole intermolecular forces and hydrogen bonds.
The polarity, dipole moment, polarizability and hydrogen bonding of a solvent determines what type of compounds it is able to dissolve and with what other solvents or liquid compounds it is miscible. Generally, polar solvents dissolve polar compounds best and non-polar solvents dissolve non-polar compounds best; hence "like dissolves like".
A polar aprotic solvent is a solvent that lacks an acidic proton and is polar. Such solvents lack hydroxyl and amine groups. In contrast to protic solvents, these solvents do not serve as proton donors in hydrogen bonding, although they can be proton acceptors. Many solvents, including chlorocarbons and hydrocarbons, are classifiable as aprotic ...

No. 17 Clemson vs. No. 8 SMU. Time: 8 p.m. | TV: ABC | Line: SMU -2.5 | Total: 55.5 The ACC title game could have the most at stake. An SMU win likely gives the conference just one team in the ...
Energy drinks have been at the center of public discourse recently—and not in a good way. Influencer-backed brands that market to minors are widely criticized. Chains like Panera have faced ...
This arises from the fact that polar solvents stabilize the formation of the carbocation intermediate to a greater extent than the non-polar-solvent conditions. This is apparent in the ΔE a, ΔΔG ‡ activation. On the right is an S N 2 reaction coordinate diagram. Note the decreased ΔG ‡ activation for the non-polar-solvent reaction ...
