Acid catalysed hydration of alkene give alcohol. In thic reaction addition of water takes place according to Markownikov's rule. Since intermediate carbocation is formed in this reaction, rearrangment of carbocation takes place. In oxymercuration-demercuration reaction hydration of alkene takes place according to markownikov's rule. Oxymercuratio-demercuration-dermercuration no rearrangement is possible. in hydroboration-oxidation hydration of alkene takes place according to anti marjownikow's addition. in HBO reaction rearrangement is not possible. both in oxymercuration-demercuation and hydroboration-oxidation, intermediate carbocation are not formed. Q. CH_(3)-C-=C-Hunderset(H_(2)O_(2)//OH^(-))overset((Sia)_(2)HB)toA, A is

The acidity of carboxylic acid is determined by the nature of the alkyl group attached and the substiuent present on it. It is affected mainly by the inductive effect of the substituent and its position with respect to the -COOH group. Electron-donating substituent tends to decrease the acidic strength whereas electron-withdrawing substituent tends to increase acidic strength. The acidic strength of aromatic carboxylic acid on the other hand depends upon both the inductive and resonance effects of the substituents. Among the following, the strongest acid is :

Stability of carbocation increases as the number of alkyl substituents bonded to positively charged carbon atom _______.

Let , solute - solvent intermolecular attraction force =F_(A) solute - solute intermolecular attraction force = F_(B) solvent - solvent intermolecular attraction force =F_(C) Match the following

Which of the following acids has the smallest dissocation constant ?

Alkylhalides have polar C-X bond and undergo nucleophilic substitution reactions. These give a variety of products with nucleophiles such as -OH, -OR, -NH_(2), -CN, -NC, -NO_(2), -ONO, RCOO^(-) , etc. They undergo mainly two types of nucleophilic substitution reactions, S_(N)1 and S_(N)2 . S_(N)1 reactions are two steps reactions which proceed through the formation of carbocations while S_(N)2 reactions are one step reaction which proceeds through the formation of transition state. The stability of carbocation and transition state determine the reactivity of alkyl halides. Arrange the following in the increasing order of reactivity towards S_(N)2 reaction:
