Following rules are used to write the IUPAC name of an organic compound. (c) Skew or Gauche conformation All other conformations in between eclipsed and staggered conformations are called skew or Gauche conformations. 1. On the Basis of Position of Functional Group. It is optically inactive due to external compensation. Priority sequence is decided by following rules : 1. To get fastest exam alerts and government job alerts in India, join our Telegram channel. Each carbon atom of cyclohexane is bonded to two types hydrogens. differ only in behaviour towards plane polarised light are called enantiomer & or optical isomers and the phenomenon is known as optical isomerism. The branch of chemistry which deals with these compounds is called organic chemistry. The groups present at the double bonded carbon atoms, must be different. The revision notes covers all important formulas and concepts given in the chapter. These are very useful summary notes with neatly explained examples for best revision of the Chemistry book. hydrogen. Free PDF download of Class 11 Chemistry revision notes & short key-notes for Chapter 12 - Organic Chemistry - Some Basic Principles and Techniques to score high marks in exams, prepared by expert Chemistry teachers from latest edition of CBSE(NCERT) books. The new bond lies along with side of the ring and has little interaction with the 1t electron cloud lying above and below the ring. Chemistry Revision Notes for Class 11 Chapter 12 Organic Chemistry - Some Basic Principles and Techniques In chapter 12 of class 11 Chemistry, students are introduced to topics like classification, nomenclature, purification and qualitative analysis of organic compounds, isomerism, organic reaction and … Generally, homolytic fission takes place in non-polar, covalent molecules in the presence of sunlight or high temperature. given above, the IUPAC name of a compound can be written as, or Prefixes + Root word + Suffixes Primary prefix + secondary prefix + Root word + primary suffix + secondary suffix. This effect is temporary. In these reactions, two groups from the same or adjacent atoms are lost and electron deficient or unsaturated compound is formed. All the members of a series have same general formula, e.g.. 3. Electrophiles or Electrophilic Reagents. In this type of isomerism, compounds have same molecular formula but different structures. (c) Meso form The compound in which half part of a molecule is the mirror image of other half, is called meso form. (iii) Tertiary carbon atom When carbon atom is attached with three other carbon atoms, it is called tertiary or 3° carbon atom. In bicycle compounds, numbering is done first in larger ring, then in smaller ring. (c) Conformers of 3 – fluoro butan – 2 – ol. These notes will provide you overview of all the chapters and important points to remember. tetrakis etc. General Organic Chemistry: Bond Fission: a) Homolytic fission: Each atom separates with one electron, leading to the formation of highly reactive entities called radicals, owing their reactivity to their unpaired electron. They do not conduct electricity because of the absence of free ions. In staggered conformation. 4. Compounds having similar physical and chemical properties but. Carbon can form compound with oxygen. e.g., C3H6O represents an aldehyde and a ketone as. These are obtained by photolysis or pyrolysis. The order of stability of singlet carbenes is. (c) E-Z isomers In E-isomer, bulkier (heavier) groups are present on the opposite side of the double bond and in Z-isomer, heavier groups are present on the same side of the double bond. 3. are said to have electron attracting or negative inductive effect (- I) while that having, smaller electron affinity than hydrogen are said to have electron releasing or positive inductive effect (+ I) e.g..
