  2. Standard enthalpy of reaction - Wikipedia

    en.wikipedia.org/wiki/Standard_enthalpy_of_reaction

    Standard enthalpy of hydrogenation is defined as the enthalpy change observed when one mole of an unsaturated compound reacts with an excess of hydrogen to become fully saturated. The hydrogenation of one mole of acetylene yields ethane as a product and is described by the equation C 2 H 2 (g) + 2 H 2 (g) → C 2 H 6 (g).

  3. Tetrahydrocannabinol - Wikipedia

    en.wikipedia.org/wiki/Tetrahydrocannabinol

    It is the principal psychoactive constituent of cannabis and one of at least 113 total cannabinoids identified on the plant. Although the chemical formula for THC (C 21 H 30 O 2) describes multiple isomers, [10] the term THC usually refers to the delta-9-THC isomer with chemical name (−)-trans-Δ 9-tetrahydrocannabinol. It is a colorless oil.

  4. Delta one - Wikipedia

    en.wikipedia.org/wiki/Delta_one

    A delta one product is a derivative with a linear, symmetric payoff profile. That is, a derivative that is not an option or a product with embedded options. Examples of delta one products are Exchange-traded funds, equity swaps, custom baskets, linear certificates, futures, forwards, exchange-traded notes, trackers, and Forward rate agreements ...

  5. Standard enthalpy of formation - Wikipedia

    en.wikipedia.org/wiki/Standard_enthalpy_of_formation

    For many substances, the formation reaction may be considered as the sum of a number of simpler reactions, either real or fictitious. The enthalpy of reaction can then be analyzed by applying Hess' law, which states that the sum of the enthalpy changes for a number of individual reaction steps equals the enthalpy change of the overall reaction.

  6. Transition state theory - Wikipedia

    en.wikipedia.org/wiki/Transition_state_theory

    All chemical transformations pass through an unstable structure called the transition state, which is poised between the chemical structures of the substrates and products. The transition states for chemical reactions are proposed to have lifetimes near 10 −13 seconds, on the order of the time of a single bond vibration. No physical or ...

  7. Δ-10-Tetrahydrocannabinol - Wikipedia

    en.wikipedia.org/wiki/Δ-10-Tetrahydrocannabinol

    Δ-10-Tetrahydrocannabinol (Delta-10-THC, Δ 10-THC, alternatively numbered as Δ 2-THC) is a positional isomer of tetrahydrocannabinol, discovered in the 1980s.Two epimers have been reported in the literature, with the 9-methyl group in either the (R) or (S) conformation; of these, the (R) epimer appears to be the more active isomer as well as the double bond in the 10th position instead of ...

  8. Tetrahydrocannabinolic acid - Wikipedia

    en.wikipedia.org/wiki/Tetrahydrocannabinolic_acid

    Tetrahydrocannabinolic acid (THCA, 2-COOH-THC; conjugate base tetrahydrocannabinolate) is a precursor of tetrahydrocannabinol (THC), an active component of cannabis. [1]THCA is found in variable quantities in fresh, undried cannabis, but is progressively decarboxylated to THC with drying, and especially under intense heating such as when cannabis is smoked or cooked into cannabis edibles.

  9. Cannabinoid - Wikipedia

    en.wikipedia.org/wiki/Cannabinoid

    Delta-1, Delta-6, and Delta 3,4-Tetrahydrocannabinol are alternative names for Delta-9, Delta-8, and Delta-6a10a Tetrahydrocannabinol, respectively. [ 73 ] A 2023 paper seeking the regulation of cannabinoid terminology coined the term "derived psychoactive cannabis products" to accurately and usefully distinguish said products whilst excluding ...
