Assertion :The S−S−S− bond angle in S8 molecule is 107.8o. Reason: S8 has a V-shape.
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 – 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
Assertion (A) Rate constant determined from Arrhenius equation are fairly accurate for simple as well as complex molecules.
Reason (R) Reactant molecules undergo chemical change irrespective of their orientation during collision.
(a) Both assertion and reason are correct and the reason is correct explanation of assertion (b) Both assertion and reason are correct, but reason does not explain assertion. (c) Assertion is correct, but reason is incorrect (d) Both assertion and reason are incorrect (e) Assertion is incorrect but reason is correct.
