  2. Chemical polarity - Wikipedia

    en.wikipedia.org/wiki/Chemical_polarity

    Two charges are present with a negative charge in the middle (red shade), and a positive charge at the ends (blue shade). In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end.

  3. Solvent - Wikipedia

    en.wikipedia.org/wiki/Solvent

    Ethyl acetate, nail polish solvent. [1] A solvent (from the Latin solvō, "loosen, untie, solve") is a substance that dissolves a solute, resulting in a solution. A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid. Water is a solvent for polar molecules, and the most common solvent used by living things; all ...

  4. Van der Waals force - Wikipedia

    en.wikipedia.org/wiki/Van_der_Waals_force

    In molecular physics and chemistry, the van der Waals force (sometimes van de Waals' force) is a distance-dependent interaction between atoms or molecules. Unlike ionic or covalent bonds, these attractions do not result from a chemical electronic bond; [2] they are comparatively weak and therefore more susceptible to disturbance.

  5. Yes–no question - Wikipedia

    en.wikipedia.org/wiki/Yes–no_question

    In linguistics, a yes–no question, also known as a binary question, a polar question, or a general question, [1] is a question whose expected answer is one of two choices, one that provides an affirmative answer to the question versus one that provides a negative answer to the question. Typically, in English, the choices are either "yes" or ...

  6. Antimony triiodide - Wikipedia

    en.wikipedia.org/wiki/Antimony_triiodide

    Antimony triiodide milled. Antimony triiodide is the chemical compound with the formula Sb I 3. This ruby-red solid is the only characterized "binary" iodide of antimony, i.e. the sole compound isolated with the formula Sb x I y. It contains antimony in its +3 oxidation state. Like many iodides of the heavier main group elements, its structure ...

  7. Functional group - Wikipedia

    en.wikipedia.org/wiki/Functional_group

    A functional group is a group of atoms in a molecule with distinctive chemical properties, regardless of the other atoms in the molecule. The atoms in a functional group are linked to each other and to the rest of the molecule by covalent bonds. For repeating units of polymers, functional groups attach to their nonpolar core of carbon atoms and ...

  8. Question - Wikipedia

    en.wikipedia.org/wiki/Question

    Question. A question mark made of smaller question marks. A question is an utterance which serves as a request for information. Questions are sometimes distinguished from interrogatives, which are the grammatical forms, typically used to express them. Rhetorical questions, for instance, are interrogative in form but may not be considered bona ...

  9. Hydrophobe - Wikipedia

    en.wikipedia.org/wiki/Hydrophobe

    In chemistry, hydrophobicity is the physical property of a molecule that is seemingly repelled from a mass of water (known as a hydrophobe). [ 1 ] In contrast, hydrophiles are attracted to water. Hydrophobic molecules tend to be nonpolar and, thus, prefer other neutral molecules and nonpolar solvents.
