Haloalkanes , Haloarenes & Phenols - Reasoning questions & Answers

NOTE -  CLICK HERE FOR DOWNLOADING THE PDF OF QUESTIONS & ANSWERS 1.) Why do haloalkenes under go nucleophillic substitution whereas haloarenes under go electophillic substitution . Ans. Due to more electro negative nature of halide atom in haloalkanes carbon atom becomes slightly positive and is easily attacked by nucleophillic reagents. While in haloarenes due to resonance, carbon atom becomes slightly negative and attacked by electrophillic reagents. reagents. 2.) When an alkyl halide is treated with ethanolic solution of KCN, the major product is alkyl cyanide where as if alkyl halide is treated with AgCN,the major product is alkyl isocyanide. Ans. KCN is ionic they can attach through C or N but C-C bond is strong than C-N bond. So alkyl cyanide is the major product but AgCN is covalent so more electronegative N can attach to C and forms isocyanides. 3.) How do primary , secondary & tertiary alcohols differ in terms of dehydrogenation? Ans. 4.) Why are th

Reasoning Questions of Organic Chemistry

Lots of questions in organic chemistry comes from the reasoning section. Each and every chapter of organic chemistry possess large number of reasoning questions. Answer of most of the question is based on resonance and inductive effect. A student must have prior knowledge of resonance and inductive effect to solve all the problems correctly. In case of halo alkanes and halo airings most of the questions comes from reactivity. Answers of all these questions are based upon resonating structure and partial double bond. In case of alcohols and phenols most of the questions are from acidic strength. Again strong knowledge of resonance and resonating structure can help in solving such type of questions. In case of aldehydes and ketones most of the questions are based on reactivity and the answer of these questions are based upon inductive effect. In case of a Amines maximum questions appears from basic strength and the answer in wall both residents as well as inductive effect
