X+ is boron-10 (5 protons, 5 neutrons, 4 electrons) Y+ is boron -11 (5 protons, 6 neutrons, 4 electrons) Z+ is aluminium (13 protons, 14 neutrons, 12 electrons) -

1) is definitely out as it requires the OH group to act as an acid and release a H+ . which is not possible in the presence of H2SO4 -

First question was explained in #17975 For the 2nd question, moles of ethanol = 2.3/46 = 0.05 mol moles of ethanoic acid expected = 0.05 mol mass of ethanoic acid expected = 3 g actual mass obtained = 60% x 3 g = 1.8 g -

The free radical is a chlorine atom. Statement 1 is wrong as its a homolytic fission -

H2So4 + CH3CH2OH --> HSo4- + [CH3CH2OH2]+ It donates a proton (acts as an acid) to ethanol -

yes, it is used to provide an acidic environment, but it is not the oxidizing agent, the KMnO4 is the oxidising agent -

Do you mean that the answer was B and not D? -

Hold on, the oxidizing agent should be the KMnO4 and not sulfuric acid -

If the question was phrased such that the temperatures (energy) of the operating system was adjusted, then a catalyst is relevant. Here, they are talking about pressure conditions. -

Yes, possible to crack with enough energy. But the issue is that they do not yield products of much commercial value in most cases -

H2SO4 + aq => H^+ + H2SO4^- Due to full dissociation at the first stage, from 1 mole of H2SO4, we will get 1 mole of H+ and 1 mole of HSO4^- HSO4^-(aq) <=> H^+(aq) + SO4^2- Due to partial dissociation at the second stage, from 1 mole of HSO4^-, we will get << 1 mole of H+ and << 1 mole of...
