Which one of the following halides can be used for Friedel-Crafts alkylation?

Thus, the correct option is (B) Isopropyl chloride is the correct answer.

Which acid can be used as catalyst in Friedel-Crafts reaction?

Sulfuric acid
Alcohols are often used as substrates in Friedel-Crafts alkylation reactions. Sulfuric acid is used as a catalyst with alcohols, forming an alkyl sulfate that reacts with the aromatic substrate.

Which of the halides are reactive in a Friedel-Crafts alkylation reaction?

This means that an RF haloalkane is most reactive followed by RCl then RBr and finally RI. This means that the Lewis acids used as catalysts in Friedel-Crafts Alkylation reactions tend have similar halogen combinations such as BF3, SbCl5, AlCl3, SbCl5, and AlBr3, all of which are commonly used in these reactions.

Which of the following aromatic compounds undergo Friedel Craft alkylation?

Explanation: Toluene will undergo Friedel–Crafts alkylation with methyl chloride and aluminum chloride as because as weak electron withdrawing functional group — will not make the ring less electron dense, hence more reactive in an aromatic electrophilic substitution as compared to electron withdrawing group (benzoic …

Which of the following halides Cannot be used in a Friedel Crafts alkylation reaction?

The carbocation of bromobenzene and vinyl halide is unstable as the positive charge will be on sp2 s p 2 carbon. Therefore, bromobenzene and vinyl halide cannot be used in the Friedel-crafts alkylation reactions. Thus, option e is the correct answer.

Which organic halide Cannot participate in a Friedel Crafts alkylation?

When more than one alkyl group is introduced into an aromatic ring during the course of a Friedel-Crafts alkylation reaction, polyalkylation is said to have occurred. The four limitations on the use of Friedel-Crafts alkylations are as follows: vinyl and aryl halides cannot be used to form carbocations.

Which compound does not give Friedel-Crafts reaction?

Nitrobenzene does not undergo Friedel-Craft’s reaction.

Which compound is used in Friedel Craft reaction?

Friedel-Crafts reaction of benzene with n-propyl chloride on heating produce isopropyl benzene.

Which Cannot be used in Friedel Craft reaction?

Friedel-Craft reaction with aryl and vinyl halide is not possible, because the lone pair of halogen undergoes conjugation with the benzene ring and double bond respectively, and forms a partial double bond. Due to this reason, only alkyl and vinyl halide cannot be used as a halide component in a Friedel-craft reaction.

Which organic halide Cannot participate in a Friedel-Crafts alkylation?

Which of the following compounds will not undergo Friedel Crafts reaction with benzene?

From all four given compounds, the option (C) compound generally will not undergo Friedel Crafts reaction with benzene because the compound (C) forms an intermediate carbocation. The halogens are chlorine that is Cl, bromine that is Br, and fluorine that is F are usually used in Friedel craft’s reaction.

Which of the following compounds will not undergo Friedel Crafts reaction easily?

Nitrobenzene does not undergo Friedel-Crafts reaction, because the nitro group in nitrobenzene is a strong withdrawal group and this group repels the electrophile from it. Hence, nitrobenzene will not undergo Friedel-Crafts reaction easily. So, the correct answer is option C.
