In the iodoform reaction using propanone, the methyl ketone group of propanone undergoes halogenation and substitution reactions with iodine and sodium hydroxide. The mechanism involves formation of the enolate ion, followed by a nucleophilic attack of the iodine ion to yield iodoform as the final product.

What happens when propanone is reduced?
When propanone is reduced, it forms propan-2-ol (isopropyl alcohol) as the main product. The reduction process involves adding hydrogen atoms to the carbonyl group of propanone, resulting in the conversion of the C=O bond to a C-OH bond.
Which 2 substances bind using a lock-and-key mechanism?
Enzymes and substrates bind using a lock-and-key mechanism. The enzyme's active site (lock) has a specific shape that fits with the substrate (key), allowing for a precise and efficient chemical reaction to occur.
What does the rate of law use to determine the rate of a reaction?
The rate of a reaction is calculated using the concentrations of reactants.
What is salkowski's reaction and its mechanism?
salkowski's reaction is carried out using salkowski's reagent (1 ml of 0.5 M FeCl3 + 50 ml of 35 % perchloric acid ). It is used for colorimetric estimation of indole derivates, it produces pink colour. A trace of hydrogen peroxide induces the oxidation reaction which produces the colour and hastening its intensity.

Can a reaction mechanism be determined without an experiment?
While theoretical approaches like computational chemistry can provide insights into reaction mechanisms, experimental validation is necessary to confirm the proposed mechanism. Experimentation allows for the observation of intermediates, rate laws, and other key details that are crucial for elucidating the complete reaction pathway. Theory and experiment are often combined to develop a comprehensive understanding of reaction mechanisms.

Methods for determination of reaction mechanism?
Monitoring reactant disappearance or product formation over time using techniques such as UV-Vis spectroscopy or chromatography can provide insight into reaction intermediates. Isotope labeling experiments can help identify the pathway of a reaction by tracing the fate of specific atoms during the reaction. Computational chemistry methods, such as density functional theory calculations, can be used to predict reaction pathways and intermediate structures. Kinetic studies, including determining rate laws and activation energies, can provide information about the steps involved in a reaction mechanism.
What does the rate of law use to determine the rate of a reaction?
The rate of a reaction is calculated using the concentrations of reactants.
Can the course of a reaction be traced by using a stable isotope?
Yes, the course of a reaction can be traced by using a stable isotope. By incorporating a stable isotope into a reactant or product molecule, its presence can be detected using various analytical techniques, such as mass spectrometry, NMR spectroscopy, or isotopic dilution. This allows researchers to track the transformation of the isotope-labeled molecule and gain insights into the reaction mechanism and kinetics.

What are the chemical tests to distinguish between cyclohexanol and phenol and what reactions are involved?
the difference between cyclohexane and cyclohexene is the difference between an alkane and an alkene. Add bromine water to both samples. cyclohexane will remain orange. cyclohexene will turn the orange solution colourless because bromine adds across the double bonds. Propanol gives effervescence of hydrogen with sodium metal, propanone does not. Propanone and 2-propanol answer iodoform test, 1-propanol does not Benzoic acid and propanoic acid gives effervescence of carbon dioxide with sodium bicarbonate, benzaldehyde and propanoic chloride does not.

How is paracetamol purified?
Paracetamol tablets can be broken up using propanone and heating them for an hour under reflux. You then filter the solids and cool the liquid. Paracetamol is insoluble in cool water. Crystals form which can then be collected using vacuum filtration
Is using alcohol during time of stress a positive coping mechanism?
No it is a negative coping mechanism.
