Assertion :1 mole H2SO4 contains same mass of oxygen and sulphur. Reason: 1 mole H2SO4 represents 98 g mass.
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 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: Be and Al have similar properties.
Reason: Be2+ and Al3+ have nearly the same charge/volume ratios and similar polarising power.
Assertion (A) Order of the reaction can be zero or fractional.
Reason (R) We cannot determine order from balanced chemical equation.
