Which of the products will be major product in the reaction givenSolution: In the given reaction, (B) is the major product of the reactions. Question 25.Which of the following compounds will give racemic mixture on nucleophilic substitution by OH ion?Solution:General Instruction: In the question 26 to 29, arrange the compounds in increasing order of rate of reaction towards nucleophilic substitution. Here, halogen atom is substituted by hydroxyl ion. Swartz reaction: It is a type of reaction in which alkyl halides are reacted with silver fluoride to obtain fluoroalkanes, it is one of the best reactions to produce fluoroalkanes. The process of conversion of enantiomer into a racemic mixture is known as racemisation. Diphenyls are potential threat to the environment. Racemic mixture 4.
