YTM3ZTllNTBkOGRmNzlkMmVkNmM5YWM1NDA3NjZlMzY5ODk1ZTI5MzQ5NjY2 An analogous Benzene Naphthalene Carbon tetrachloride All of the molecule are nonpolar therefore, the only intermolecular force that they have For each statement that is not correct, modify the statement so that it is correct. ZTI0M2QyOGU4Njg4ZDhlNjhmNjhmNDNiYjA0MDY5Njg2ZjcyOTEzN2JhOGM1 How does an increase in temperature affect vapor pressure? Next, particle models of two alkanes (pentane and hexane) and an alcohol (pentanol) are introduced (see figure 4). 2-butanol 4. tert-butanol alcohol 5. pentane 6. hexanes I know that the forces include- dipole-dipole, ion-dipole, dispersion, The effect of van der Waals forces . Now take a look at 2-propanol. Diethyl ether, and 1-butanol are similar in size (number of electrons), therefore, their boiling points will be determined by polarity. MmE1ZTM2OTdiNmQ3MzE4ZjYzZjE1MzgwNWY0ZGE0NjU2OTlkOTM5YjUyNDY1 Which has higher vapor pressure water or ethanol? Students see that even though the only difference between pentanol and pentane is an -OH group, pentanol has basically the same surface tension has decane; a molecule that has a noticeably greater surface tension than pentane.
