Sublimation - Purification of organic compounds
Specific organic solids on heating directly change from solid to vapour state without passing via a liquid state, such types of substances are known as sublimable and this procedure is called sublimation. The sublimation process is employed for the separation of sublimable volatile compounds from non sublimable impurities. The process is usually employed for the purification of camphor, anthracene, naphthalene, benzoic acid NH4Cl,HgCl2, solid SO2, Iodine and salicylic acid etc containing non-volatile impurities.
Explain the geometry of CCl4 We first have to know the geometry of CCl4. This should be easy: it's tetrahedral, because the carbon is bonded to four identical groups. Now, as s
