How do I rank the following compounds from lowest to

Solution for Which one of the following pure substances should have the lowest boiling point? A HCl B H2S C CH4 D CH3OH E NH 1% glucose will have Vant Hoff factor 1, 1% sucrose will have Vant Hoff factor 1. Also, 1% NaCl will have Van't Hoff factor 2 and 1 % C aC l2. . will have Vant Hoff factor i as 3. Thus 1% C aC l2. . produces most ions and thus lowers the freezing point to the maximum value. The correct option is D The boiling point of alcohol (78°C or 351K) is lower than that of water (100°C or 373K), therefore, alcohol is more volatile than water. Liquids have only one free surface. Liquids show the property of diffusion. The reason being that a ether has very low boiling point (308 K). Therefore, it evaporates quite rapidly

A) BrI B) CsI C) LiI D) NaI E) RbI. 3. Which one of the following substances is expected to have the highest boiling point? As a general rule, when frying foods, it is important to choose an oil with a very high smoking point. Most foods are fried between the temperatures of 350 F and 450 F so it is best to choose an oil with a smoking point above 400 F. Fats and oils with lower smoking points, like butter and olive oil, are best suited for lower temperature cooking. Answer: Of the diatomic elements (H2, N2, O2, F2, Cl2, Br2, I2), all have dispersion forces.

Life is a characteristic that distinguishes physical entities that have biological processes, such as signaling and self-sustaining processes, from those that do not, either because such functions have ceased (they have died), or because they never had such functions and are classified as inanimate.Various forms of life exist, such as plants, animals, fungi, protists, archaea, and bacteria SiH4 will have the lowest boiling point. H2O has the highest boiling point because it has hydrogen bonding, so it takes more energy to break molecules apart. HCl, H2S and PH3 have dipole-dipole bonds, so they are stronger than the intermolecular forces of SiH4. Thus, SiH4 has the weakest bonds, so it takes the least amount of energy to break. The boiling point depends on the intermolecular forces between the molecules of the compound. have dipole- dipole interactions because there is the difference in electronegativity values of the atoms in the molecules. posses hydrogen bonding

(a) NH₃. Helium is nonpolar and by far the lightest, so it should have the lowest boiling point. Argon and N 2 O have very similar molar masses (40 and 44 g/mol, respectively), but N 2 O is polar while Ar is not. Consequently, N 2 O should have a higher boiling point 3 have weak dispersion forces only, so have the lowest boiling points. CH 3CH 2CH 2CH 3 has more atoms, so more dispersion forces and hence the higher boiling point of the two. CH 3CH 2OCH 2CH 3 is similar in size to CH 3CH 2CH 2CH 3, but has dipole-dipole forces as well due to the presence of polar C-O bonds. Thus, the boiling point of CH 3CH.
