NEET Exams |
| Organic Chemistry – Some Basic Principles and Techniques | |
| Aliphatic Compounds | Straight or branched chain compounds
E.g. Ethane, Isobutane, Acetaldehyde, Ethanol, etc. |
| Aromatic Compounds | Commonly called ‘arenes’. They have a ring system with a planar structure and (4n + 2) π electrons that are delocalised in the ring
E.g. Benzene, Naphthalene, Cyclopentadienyl anion, Toluene, etc. |
| Metamerism | Different alkyl chains on either side of the functional group of the molecule, e.g. methoxypropane (CH3OC3H7) and ethoxyethane (C2H5OC2H5) |
| Stereoisomerism | Difference in relative positions of atoms or groups in compounds with same constitution and sequence of covalent bonds
Geometrical and optical isomerism |
| Nucleophiles | Nucleus seeking reagent that donates an electron pair. They are negatively charged ions or neutral molecules with lone pair of electrons
E.g. hydroxide (HO– ), cyanide (NC–) ions and carbanions (R3C–), H2O, R3N, R2NH, etc. |
| Electrophiles | Electron seeking reagent that accepts an electron pair
E.g. carbocations, carbonyl group (>C=O) or alkyl halides, etc. |
| Inductive Effect | An ability of substituent(s) to either withdraw or donate electron density to the attached carbon atom
Electron withdrawing groups – halogen, -NO2, -CN, -COOH, -COOR, etc. Electron donating groups – alkyl groups |
| Positive Resonance Effect (+R effect) | Transfer of electrons away from an atom or substituent group attached to the conjugated system
E.g. – halogen, –OH, –OR, –OCOR, –NH2, –NHR, –NR2, –NHCOR |
| Negative Resonance Effect (-R effect) | Transfer of electrons towards the atom or substituent group attached to the conjugated system
E.g. – COOH, –CHO, >C=O, – CN, –NO2 |
| Electromeric Effect (E effect) | Positive Electromeric Effect (+E effect) – The π−electrons of the multiple bonds are transferred to the atom that gets attached to the reagent
Negative Electromeric Effect (–E effect) – The π−electrons of the multiple bonds are transferred to the atom that does not get attached to the reagent |
