A compound composed of only carbon and hydrogen is 7.743% hydrogen by mass. The compound has a molar mass of 26.04 g/mol. Propose a Lewis structure for the compound. 8. Use Lewis structures to explain why both Br_3- and l_j" ions are stable, while the F_3 ion is unstable and has not been observed.
Question 17 4 pts Carbon dioxide has a higher boiling point than nitrogen dioxide because carbon dioxide is linear and non-polar. True O False
Part A H,0 (100°C) has a higher boiling point than CH, OH (65°C). There are more hydrogen bonds between water molecules than between alcohol molecules. There are less hydrogen bonds between water molecules than between alcohol molecules. CH, OH has the higher molecular mass than H,O. There are no hydrogen bonds between alcohol molecules while there are plenty of them between water molecules. O Submit Previous Answers Request Answer X Incorrect; Try Again; 2 attempts remaining Part B H,O (100°C)...
2. Water (H2O) molecules experience dispersion, dipole-dipole and hydrogen bonding forces. Octane (CH3-CH2- CH2- CH2- CH2- CH2- CH2- CH3) molecues experience dispersion forces only. Water boils at 100 0C, whereas octane boils at 125.6 0C. Briefly explain why octane has the higher boiling point temperature
The boiling point of iodine (12) is much higher than the boiling point of helium (He). Why? O 12 has a larger electron cloud than He, so more energy is required to overcome the stronger London Dispersion Forces. O It requires more energy to break the covalent bonds in 12 than to overcome the London Dispersion Forces between He atoms. The bonds between iodine atoms are stronger than the bonds between helium atoms and therefore harder to break. O 12...

2 Why is the boiling point of ammonia higher than the boiling point of ethane? What type of interaction is responsible for sodium chloride's very high melting point? A 5. What type of interaction is responsible for water's high boiling point? 4 A gaseous sample of a compound has a gas density of 0.647 g/L at 694 torr and 20 °C. What is the molar mass of this compound? If this compound contains only nitrogen and hydrogen, and is 82.2%...
C The boiling point of H,O is much higher than the boiling point of HS. H2O is a molecular compound, while HS is an ionic compound. H2O is a polar molecule, so the attractions between the molecules are stronger than those between nonpolar H2S molecules. H2O has strong hydrogen bonds between its molecules, and HS molecules cannot form hydrogen bonds. The dispersion forces between the H2O molecules are much stronger. d The boiling point of CH,O is much higher than...
Ethers have... o higher than expected boiling point o low boiling points hydrogen bond towards eachother O none of these
why does HCN have a higher boiling point than FCN? ( has to do with intermolecular forces?)
