Types OF Alkyl Group || Alkenyl Group || Common Naming on The Basic Alkyl Group

Oxidation OF alkyl Benzene Group

Assertion (A) : Tertiary alkyl halides are more reactive than 1^(@) alkyl halides towards elimination. Reason (R ) : Positive Inductive effect of alkyl groups weakens carbon-halogen bond in 3^(@) halides.

|| (Halogen Derivatives) || method OF preparation OF alkyl halide || Introduction to the type OF organic chemical reaction ||

In the following questions, a statement of assertion (A) is following by a statement of reason (R ) A : Halogen is deactivating group due to -I effect. R: Halogen is ortho -para directing due to +M effect .

Read the passage given below and answer the following questions: Alkyl/Aryl halides may be classified as mono, di or polyhalogen compounds depending on one, two or more halogen atoms in their structures. Alkyl halides are prepared by free radical halogenation of alkanes, addition of halogen acids to alkenes and replacement of -OH group of alcohols with halogens using phosphorus halides, thionyl chloride or halogen acids. Aryl halides are prepared by electrophilic substitution to arenes. The following questions are multiple choice questions. Choose the most appropriate answer: Name the major monohalo product following reaction:
