Which of the following statement(s) is/are incorrect regarding property of alkali metals ? I. Alkali metal on reaction with water produces a gas as a by product which burns with popping sound. II.All alkali metal hydrides are ionic in nature.

The given reaction occurs in a car battery when it is used to produce electricity. Pb + PbO_2 + 2H_2 SO_4 to 2PbSO_4 + 2H_2 O Which of the following statements are incorrect about this reaction? I. Pb is acting as an oxidising agent. II. H_2 SO_4 is acting as a reducing agent. III. The reaction is a precipitation reaction. IV. PbO_2 oxidises Pb to PbSO_4

The alkenes have pi -bonds which make them highly reactive. These undergo electrophilic addition reactions, Addition of HX to unsymmetrical alkenes gives two products and follow Markovnikov rule and anti- Markovnikov rule. The addition occure through the formation of carbocation in Markovnikov rule and free radicals in anti-Markovnikov zule. The ozonolysis reaction of alkenes helps to locate the position of double bond. Write the major product in the following reaction: CH_(3)- overset(CH_(3))overset(|)CH-CH=CH_(2) overset(HBr)to

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. Write the main products A and B in the following reaction. A overset(KNO_(2))larr CH_(3)CH_(2)Br overset(AgNO_(2))to B .
