4. Wurtz reaction Wurtz reaction can be used in organic chemistry, organometallic chemistry and in polymers. It is a kind of coupling reaction. The mechanism begins with a single electron transfer (SET) from sodium metal to the alkyl halide, which dissociates to form an alkyl radical and sodium halide salt. Another molecule of sodium performs another SET to the alkyl radical to form a nucleophilic carbanion . The carbanion then attacks another molecule of alkyl halide in a nucleophilic substitution reaction (SN2) to form the final coupled product and another molecule of sodium halide salt.   2R–X + 2Na → R–R + 2Na + X −

5. Aldol reaction Aldol name is derived from  ald ehyde & alcoh ol   Aldol reaction is powerful because it unites two relatively simple molecules into a more complex one.   Definition   When enolate of an aldehyde or a ketone reacts at the  α-carbon with the carbonyl of another molecule under basic or acidic conditions to obtain β- hydroxy aldehyde or ketone , this reaction is called Aldol Reaction.

6. Neurine Neurine is an alkaloid found in egg yolk, brain, bile and in cadavers. It is formed during putrefaction of biological tissues by the dehydration of choline . It is a poisonous, syrupy liquid with a fishy odor. Neurine is a quaternary ammonium salt with three methyl groups and one vinyl group attached to the nitrogen atom.
