DIRECTIONS: Read the passage given below and answer the question that follow :A hydrocarbon (X) of the formula C6H12 does not react with bromine water but react with bromine in presence of light, forming compound (Y). Compound (Y) on treatment with Alc. KOH gives compound [Z] which on ozonolysis gives (T) of the formula C6H10O2. Compound (T) reduces Tollens reagent and gives compound (W). (W) gives iodoform test and produce compound(U) which when heated with P2O5 forms a cyclic anhydride (V)
The bond energy (in kcal mol–) of a C–C single bond is approximately
C – C bond energy= 348 kJ/mol = \(\frac{348}{4.2}\)kcal/mol
= 82.85 kcal/mol ≈ 100kcal/mol
The synthesis of 3-octyne is achieved by adding a bromoalkane into a mixture of sodium amide and an alkyne.The bromoalkane and alkyne respectively are
Ozonolysis of an organic compound ‘A’ produces acetone and propionaldhyde in equimolar mixture. Identify ‘A’ from the following compounds:
One mole of a symmetrical alkene on ozonolysis gives two moles of an aldehyde having a molecular mass of 44u. Thealkene is
Writing the reaction we get
CH3MgX + CH3 –C = C–H ⟶ CH3 –C = CMgX + CH4(g)
