Fthanal has almost the same molar mass (46.07 g/mol), but boils at 78.5°. Which of he following BEST explains the reason for the large discrepancy in boilig poirnt? Choose one: A Propane is ionic and, thcrefore, has a lower boiling point. B. Ethanol is ionic and, thercforc, has a higher boiling point O C. Poth compounds only cxhibit vanderWaals forccs. D. Both compounds arc polar. Ethanol is morc polar than Propanc C. Cthunol exhibits hydrogen bonding. Propane exhibits hydrogen bonding. 1325 > 110F25QUESTIONS COMPLETED Type here to search 1000 PM 11/29/2017Explanation / Answer
Q1)
Ethanol boils at a higheer temperature than propane due to the presence of intermolecular Hydrogen bonding present between ethanol molecules while in propane it is absent.
Thus your correct choice is option E only.
Q2) Br- is an ion that is surrounded by water molecules which are dipoles (O with partial negative charge and H wit partial positive charge.)
Thus the forces of attraction between Br- and water are ION - DIPOLE INTERACTIONS.
OPTION D
