Assertion :SO3 has a planar structure Reason: Sulphur atom in SO3 is sp2 hybridised and O−S−O bond angle in 120o
SO3 has a tirgonal planar structure with bond angle 120°. The representation of SO3 molecule is shown below.
Assertion (A) Bond angle in ethers is slightly less than the tetrahedral angle. Reason (R) There is a repulsion between the two bulky (- R) groups. (a) Assertion and reason both are correct and reason is correct explanation of assertion. (b) Assertion and reason both are wrong statements. (c) Assertion is correct statement but reason is wrong statement. (d) Assertion is wrong statement but reason is correct statement. (e) Both assertion and reason are correct statements but reason is not correct explanation of assertion.
Assertion (A) Phenols give o-and p-nitrophenol on nitration with conc. HNO3 and H2SO4 mixture. Reason (R) - OH group in phenol is o-,p-directing. (a) Assertion and reason both are correct and reason is correct explanation of assertion. (b) Assertion and reason both are wrong statements. (c) Assertion is correct statement but reason is wrong statement. (d) Assertion is wrong statement but reason is correct statement. (e) Both assertion and reason are correct statements but reason is not correct explanation of assertion.
Assertion – The non-fusible impurities present in iron ore are removed by CaCO3 .
Reason: CaCO3 which decomposes into CaO and CO2. The CaO formed reacts with SiO2 to remove silica
