Learnengineering.in collected the various Topic wise notes for JEE(Joint Entrance Exam).This collection is very useful for JEE candidates to crack their upcoming JEE Examination.. Organic compounds are the compounds mainly consisting of C and H atoms, along with some atoms like O,N, Halogens occasionally. This is the currently selected item. IUPAC Nomenclature Naming Molecules by Following the Rules What alkyl groups do you see? *remember the rule – “likes dissolve likes” O - H + + H 4) They have low melting points – due to weak intermolecular forces. To avoid long and tedious names in normal communication, the official IUPAC naming recommendations are not always followed in practice, except when it is necessary to give an unambiguous and absolute definition to a compound. ; An organic compound in general will have two names – common name and IUPAC name.

Created: Oct 14, 2012 | Updated: Dec 9, 2014 thanks, Jane for the comment, Hopefully the worksheet is now improved I reckon that the worksheet would take about 20-25 minutes or even longer. Molecules which have the same molecular formula, but different connectivities among the constituent atoms, are called structural isomers. The structural isomers having the formula C4H10 are shown below. View … Step-I : Selection of parent chain: The longest continuous carbon chain is selected as the parent chain. Organic compounds are the compounds mainly consisting of C and H atoms, along with some atoms like O,N, Halogens occasionally.
