Question & Answer: The surface tension and viscosity values for diethyl ether, acetone, ethanol, and ethylene…..

5·The surface tension and viscosity values for diethyl ether, acetone, ethanol, and ethylene glycol are shown here. Compound Surface Tension (mN/m) Viscosity (mPa s) Molecule diethyl ether 17 0.22 23 0.31 ethanol C2HGOH 1.07 ethylene glycol CH(OH)CHlOH) 48 16.1 (a) Explain their differences in viscosity in terms of the size and shape of their molecules and their IMFs. (b) Explain their differences in surface tension in terms of the size and shape of their molecules and their IMFs: 6. Carbon tetrachloride, CCl4, was once used as a dry cleaning solvent, but is no longer used because it is carcinogenic. At 57.8 °C, the vapor pressure of CCl4 is 54.0 kPa, and its enthalpy of vaporization is 33.05 kJ/mol. Use this information to estimate the normal boiling point for CCl.

(a) Explain their differences in viscosity in terms of the size and shape of their molecules and their IMFs. (b) Explain their differences in surface tension in terms of the size and shape of their molecules and their IMFs: Carbon tetrachloride, CCl_4, was once used as a dry cleaning solvent, but is no longer used because it is carcinogenic. At 57.8 degree C, the vapor pressure of CCl_4 is 54.0 kPa, and its enthalpy of vaporization is 33.05 kJ/mol. Use this information to estimate the normal boiling point for CCl_4.
