Question. Which one of the following are correctly arranged on the basis of the property indicated:
(a)I2< Br2<F2<Cl2 [ increasing bond dissociation enthalpy]
(b) H2O > H2S<H2Te<H2Se [ increasing acidic strength]
(c) NH3 < N2O< NH2OH<N2O5 [ increasing oxidation state]
(d) BiH3<SbH3<AsH3<PH3<NH3 [ increasing bondangle]
Answer: (d) BiH3<SbH3<AsH3<PH3<NH3 [ increasing bondangle] correct order
