Write the structures of different isomers corresponding to the molecular formula C_(3)H_(9)N . Write IUPAC names of the isomers which will liberate nitrogen gas on treatment with nitrous acid.
Consider the following statements : a. The hydronium ion (H_(3)O^(+)) is the strongest acid that can exist in aqueous solution . b. Mixing concentrated acid or bases with water is a highly endothermic reaction . Which of these statement (s) is / are correct ?
Compounds A (C_(10) H_(10)) decolourises Br, in C CI_4 Ozonolysis of A gave B (C_(10) H_(10),O_2) . B reacts hydrazine and base followed by heating in ethylene glycol gave a hydrocarbon C (C_(10) H_(14)) C on oxidation gave a dicarboxylic acid which form anhydride easily. Conversion of B to C is called
