  • 18:3418:34, 19 February 2024 diff hist −11 Sodium hydride Corrected: most of the other “molecular hydrides” listed (CH4, NH3, H2O, HF) were not hydrides because the H-X bond is polarized towards the X, not toward the H as it would be in a hydride. Changed it to list actual molecular hydrides Tags: Mobile edit Mobile web edit

  • 13:0413:04, 24 June 2023 diff hist −21 Thiodiglycol The phrase “has polar and nonpolar solvent propeties” is meaningless without further explanation. The rest of the paragraph does not elaborate on the nonpolar aspect - so I changed it to reflect the fact it is a polar solvent Tags: Mobile edit Mobile web edit

  • 06:1806:18, 17 April 2020 diff hist +6 Amino acid Changed the title image since the original image had incorrect relative atomic radii (oxygen and nitrogen were depicted as larger than carbon, but in actuality they are smaller than carbon), incorrect orientation of the acid (the H was down, not up), and the incorrect bond angles shown around the molecule.
