Assertion :The order of stability of carbanion are (C6H5)3C−>C6H5CH−2>allyl>CH−3>(CH3)2CH− Reason: The stabiliby of carbanions is influenced by both resonance and inductive effects.
Assertion (A) Order and molecularity are same.
Reason (R) Order is determined experimentally and molecularity is the sum of the stoichimetric coeffcient of rate determining elementary step.
(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.
ASSERTION: n-Pentane and n-Hexane belong to a homologous series.
REASON: n-Pentane and n-Hexane belong to the same class of hydrocarbons and they differ by a - CH2 - group.
Assertion (A) Order of the reaction can be zero or fractional.
Reason (R) We cannot determine order from balanced chemical equation.
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
