In this reaction, alkanes are prepared from alkyl halides by using Na, dry ether. 61. This is because the two different alkyl halides not only react with each other but also react among themselves. If the alkyl halide has more chemical reactivity than the aryl halide, it will form the carbon sodium bond first and act as a nucleophile to the aryl halide, helping the reaction in forming asymmetrical products. Q9. During the cracking of alkanes, why do the C-C bonds break instead of the C-H bonds? What is the constant ratio between 3 9 27 81? The reaction can also be conducted using metals other than sodium (such as potassium, iron, copper, and lithium). . Hence, Br2 cannot differentiate between ethene and ethyne. The Wurtz-Fittig reaction is a chemical process that produces substituted aromatic compounds from aryl halides, alkyl halides, sodium metal, and dry ether. 58. 8.
