Did you know?
WebConformations of C symmetry occur exclusively in crystalline ethanethiol and Crystals II of 2-propanethiol and show up more prominently in the spectra of the liquids and glasses. However, both C and C forms occur in Crystals I of 2-propanethiol. Energy differences between the forms were estimated from calorimetric data. WebFeb 7, 2016 · Note: However, ethanol molecules have a much more powerful intermolecular force available to them, which is hydrogen bonding. So, clearly, ethanol molecules have a higher boiling point or whatnot than ethanethiol. Just to make sure that this is clear enough.
