What is the role of methanol in the extraction of chlorophyll?
Methanol is commonly used as a solvent in the extraction of chlorophyll because it is highly polar and can effectively dissolve chlorophyll from plant material. Additionally, methanol helps to break down cell walls and release chlorophyll into the solvent, making it easier to extract. After extraction, methanol can be evaporated to leave the chlorophyll behind.
Why is it important to blow out the flame before the methanol is completely consumed?
Burning to dryness can cause your watch glass to break. Burning all the methanol allows for contamination to occur. Burning all the methanol off creates a dangerous flame. Burning to dryness can cause your watch glass to break. Burning all the methanol creates a hotter surface as the flame is trying to burn the dry salts. Blow out the flame before the methanol is completely consumed.
Why is methanol a weak electrolyte?
Methanol is a weak electrolyte because it does not dissociate completely into ions in solution. While a small portion of methanol molecules may break apart into ions, most remain intact as neutral molecules. This results in a low concentration of ions in solution, making it a weak electrolyte.
What method use to break surface tension?
a) Increasing the temperature of the solution b) Adding ethanol, methanol or other alcohols
Which type of bonding explains why methanol has a much higher boiling point that methane?
Methanol has a much higher boiling point than methane due to hydrogen bonding. In methanol, the presence of an -OH (hydroxyl) group allows for strong intermolecular hydrogen bonds between methanol molecules, whereas methane only exhibits weaker van der Waals forces. These hydrogen bonds require more energy to break, resulting in a higher boiling point for methanol compared to methane.
Why does methanol show an exothermic reaction with water at room temperature while it gives an endothermic reaction with water in cold conditions?
Methanol can form hydrogen bonds with water molecules, leading to an exothermic reaction due to the release of energy when the bonds are formed. In colder conditions, the stronger hydrogen bonds between water molecules dominate, requiring energy to break these bonds to accommodate methanol molecules, resulting in an endothermic reaction.
Why does Cu have a greater boiling point than methanol CH3OH?
Cu has a lower boiling point than CH3OH because its particles are less polar. the CH3OH molecules have to have more kinetic energy to break the bonds between them and the surrounding molecules.
Why methane mercaptan has a lower boiling point than methanol even though methyl mercaptan has a higher molecular weight?
For the same reason that water isn't a gas. Oxygen is highly electronegative and the hydrogen bonding present in water and methanol raises the intermolecular attractive forces and results in a higher boiling point.
Is methanol a volatile liquid at room temperature true or false?
ethanol Edit- this would be methanol because ethanol is a 2-carbon chain compared to the 1C in ethanol, and therefore has more intermolecular forces. As a result, molecules of ethanol would need more energy to break these intermolecular forces to be in a gaseous phase.
What is wiper fluid made of?
Wiper fluid is mostly water, with enough methanol added to prevent freezing, and a small amount of detergent to help break away bug scum.
Do covalent bond break into ions?
Sometimes, but not usually. The covalent bond in HCl, for example, breaks when the gas is dissolved in water, but the bonds in methanol, acetone, and most other organic compounds do not.
Is phthalic anhydride is soluble in methanol?
Phthalic anhydride is slightly soluble in methanol. But beware! In this case, phthalic anhydride will actually react with its solvent. This is called estrification of the anhydride. Methanol will break the ring of Phthalic anhydride and make an ester. C6H4(CO)2O + CH3OH --> C6H4(CO2H)(CO2CH3) Similarly, you might THINK Phthalic anhydride is soluble in water, but it actually reacts with water to make phthalic acid. If you want to make a true solution of phthalic anhydride, I would recommend acetone, or methylethyl ketone.
