What is the difference between acetone and methyl ethyl ketone?
Chemically the difference is 1 carbon and 2 hydrogen atoms. Acetone ==> CH3-CHO-CH3 MEK (Butanone) ==> CH3-CHO-CH2-CH3 Their properties are therefore very similar because of this. MEK HARMFUL OR FATAL IF SWALLOWED. HARMFUL IF INHALED OR ABSORBED THROUGH SKIN. CAUSES IRRITATION TO SKIN, EYES AND RESPIRATORY TRACT. AFFECTS CENTRAL NERVOUS SYSTEM. Acetone HARMFUL IF SWALLOWED OR INHALED. CAUSES IRRITATION TO SKIN, EYES AND RESPIRATORY TRACT. AFFECTS CENTRAL NERVOUS SYSTEM Acetone also happens to be much cheaper. As for uses, since acetone evaporates quicker it is often used as a paint thinner as it will not prolong the drying time as much as MEK would. Acetone is also a better solvent because looking at the structure of the molecule it has a more medium polarity than MEK, and thus dissolves a wider range of compounds.
Why is CH3OH methyl alcohol?
CH3OH is called methyl alcohol because it is a type of alcohol compound where the hydroxyl group (-OH) is attached to a carbon atom (methyl group -CH3) in the molecule. This naming convention is based on the IUPAC system for naming organic compounds.
What happens if exactly 0.3 equivalent of base is added to a solution of fully protonated acetic acid (pKa 4.76)?
When 0.3 equivalents of base are added to a solution of fully protonated acetic acid, which is predominantly in its protonated form (CH₃COOH), the base will deprotonate some of the acetic acid, forming acetate ions (CH₃COO⁻). Since the pKa of acetic acid is 4.76, the addition of the base will shift the equilibrium towards the formation of acetate. The resulting solution will contain a mixture of acetic acid and acetate, leading to a buffer system that can resist pH changes. The pH of the solution will increase, but it will remain below the pKa, indicating that acetic acid is still the predominant species.
Why should methyl alcohol never be used medicinally?
Methyl alcohol, also known as methanol, should never be used medicinally because it is highly toxic and can cause severe damage to the nervous system, liver, and other organs. Ingesting or using methyl alcohol internally can lead to blindness, respiratory distress, and even death. It is not suitable for medical use and should not be consumed or used as a substitute for ethanol (drinking alcohol).
What are three functional groups found in cortisol?
Three functional groups found in cortisol are a ketone group in the carbonyl position, a hydroxyl group at C-11, and a cyclopentanoperhydrophenanthrene ring system.

What is a saturated ketone?
A saturated ketone is one which has saturated alpha, beta carbons etc.. (by this I mean saturated with hydrogens, there are no double bonds). The opposite, a conjugated ketone, is one which has double bonds in its substituents or R groups (such as an aromatic ring system or alkene). For example, benzil is a conjugated ketone while acetone is a saturated ketone. Source: Organic Chemistry student

How can one effectively name esters in organic chemistry?
To effectively name esters in organic chemistry, use the IUPAC naming system. Start with the alkyl group from the alcohol part of the ester, followed by the carboxylic acid part with an -oate ending. For example, methyl ethanoate is the IUPAC name for the ester formed from methanol and acetic acid.
What is the Rf value of methyl orange?
The Rf value of methyl orange depends on the solvent and the stationary phase used in the chromatography experiment. However, in a common solvent system like 50:50 water:ethanol, the Rf value of methyl orange is around 0.75.
Distribution coefficient of acetic acid in butanol water system?
The distribution coefficient of acetic acid in a butanol-water system is a measure of how a solute (acetic acid) distributes between the two immiscible solvents (butanol and water) at equilibrium. It is calculated as the concentration of acetic acid in butanol phase divided by the concentration in water phase. The distribution coefficient depends on factors such as solute-solvent interactions, temperature, and the nature of the solvents.
How do you indicate that a methyl group is attached to the second carbon atom in a hydrocarbon?
To indicate that a methyl group is attached to the second carbon atom in a hydrocarbon, you use the IUPAC naming system. You would name the base hydrocarbon chain and then use a locant (number) to specify the position of the methyl group. For example, if the base hydrocarbon is butane and a methyl group is attached to the second carbon, it would be named 2-methylbutane. The number "2" indicates the position of the carbon to which the methyl group is attached.
What are the risk of acetic acid?
Acetic acid can cause irritation to the skin, eyes, and respiratory tract if not handled properly. Ingesting large amounts can lead to abdominal pain, nausea, and vomiting. Prolonged exposure to high concentrations of acetic acid can also damage the respiratory system.
What is the difference between acetic acid and ethanoic acid?
There is no difference between acetic acid and ethanoic acid - they are the same compound with the chemical formula CH3COOH. "Acetic acid" is the common name used in the IUPAC nomenclature system, while "ethanoic acid" is the systematic (or traditional) name for the compound.
What are the potential health hazards associated with exposure to acetic acid?
Exposure to acetic acid can cause irritation to the skin, eyes, and respiratory system. Inhaling high concentrations of acetic acid can lead to coughing, shortness of breath, and lung damage. Ingesting acetic acid can result in burns to the mouth, throat, and stomach. Prolonged or repeated exposure may also cause long-term health effects such as respiratory issues and skin sensitization.
If you sprinkle dilute acetic acid over your french fries is it bad for you?
Sprinkling dilute acetic acid, which is essentially vinegar, on your french fries in small amounts is generally safe for consumption. Acetic acid is a weak acid commonly used in food preparation and preservation. However, consuming large quantities of acetic acid can potentially irritate the digestive system and may not be suitable for individuals with certain medical conditions. It is always best to use acetic acid in moderation and consult with a healthcare provider if you have any concerns.
Is acetic acid dangerous for humans?
Concentrated acetic acid (glacial) is pretty corrosive and has a terrible harsh fume. Drinking that is very dangerous as it can corrode and inflame the digestive tract. Diluted acetic acid as vinegar won't do much harm to you as long as you don't drink too much of it.
