Q. What intermolecular forces are in NaCl?
Dipole-dipole forces are probably the simplest to understand. You probably already know that in an ionic solid like NaCl, the solid is held together by Coulomb attractions between the oppositely-charges ions. The Na+ and Cl- ions alternate so the Coulomb forces are attractive.
Q. Which type of intermolecular forces exist between NaCl and h2o?
1) When NaCl is added to water is dissociates into Na+ & Cl- . The ions attracted to neutral H2O, leading to specific orientation of water molecules these forces are called charge-dipole forces.
Q. What intermolecular force of attraction is present between salt and water?
Essentially, a tug-of-war ensues with the water molecules winning the match. Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows.
Q. What type of interaction will occur between Na and h2o?
This is an ion-dipole interaction.
Q. What is the example of methanol?
Methanol is a nondrinking type of alcohol (also known as wood alcohol and methyl alcohol) which is mostly used to create fuel, solvents and antifreeze. A colorless liquid, it is volatile, flammable, and unlike ethanol, poisonous for human consumption.
Q. What is the difference between ethanol and methanol?
Ethanol and methanol are just two kinds of alcohols. Ethanol, that is also known as ethyl alcohol falls with the chemical structure with two carbon atoms. While methanol, also known as methyl alcohol is composed of only one carbon atom. However, methanol and ethanol are different types of alcohol or chemicals.
Q. How can you tell the difference between methanol and ethanol?
Ans: Iodoform test is used to distinguish between the Methanol and Ethanol. As ethanol is warmed with iodine in the presence of NaOH, it produces a yellow-coloured precipitate but methanol does not react positively to the Iodoform test.
Q. What happens when you mix ethanol and methanol?
The chemical depresses the central nervous system in the same way as ethanol, so in large quantities, it can kill someone in the same way as ordinary alcohol poisoning, but according to the National Institutes of Health, even 2 to 8 ounces of methanol can be fatal to an adult.
Q. Why can we drink ethanol and not methanol?
Ethanol and methanol are very similar in appearance and colour, so when someone drinks an alcoholic beverage, they cannot know whether it contains dangerous amounts of methanol, whether it is because it was adulterated or because the distillation process was incorrect.
Q. Which is a better solvent ethanol or methanol?
Ethanol has been known as a good solvent for polyphenol extraction and is safe for human consumption. Methanol has been generally found to be more efficient in extraction of lower molecular weight polyphenols, whereas aqueous acetone is good for extraction of higher molecular weight flavanols [6].
