Document Summary

An atom other than carbon or hydrogen uneven distribution of electron density when bonded to carbon or hydrogen. An atom or group of atoms in a molecule imparting some characteristic physical or chemical property, altering the reactivity of the molecule at that site. Separate compounds from a mixture based on different polarities. Separation depends on strength of interaction with the stationary phase, all soluble in mobile phase. Paper chromatography: (solid/liquid: stationary phase paper, mobile phase solvent. Thin layer chromatography (tlc): (solid/liquid: stationary phase thin layer of silica gel on glass (highly polar, can participate in h bonding, mobile phase organic solvent ethyl acetate with 5% acetic acid. Column chromatography: (solid/liquid: stationary phase silica gel, but packed in a column. Gas chromatography: (gas/liquid: stationary phase high boiling point liquid, mobile phase carrier gas (cid:1844)= (cid:1856)(cid:1871)(cid:1872)(cid:1866)(cid:1855)(cid:1857) (cid:1872)(cid:1867) (cid:1871)(cid:1865)(cid:1868)(cid:1864)(cid:1857) (cid:1871)(cid:1868)(cid:1867)(cid:1872) (cid:1856)(cid:1871)(cid:1872)(cid:1866)(cid:1855)(cid:1857) (cid:1872)(cid:1867) (cid:1871)(cid:1867)(cid:1864)(cid:1874)(cid:1857)(cid:1866)(cid:1872) (cid:1858)(cid:1870)(cid:1867)(cid:1866)(cid:1872) Always less than or equal to 1.
