A student was preparing aniline in the lab. She took a compound “X” and
reduced it in the presence of Ni as a catalyst. What could be the compound “X”
Which of the following compound gives an oxime with hydroxylamine:
Assertion (A): [Mn(CN)6]3– has a magnetic moment of two unpaired electrons.while [MnCl6]3– has a paramagnetic moment of four unpaired electrons.
Reason (R): [Mn(CN)6]3– is inner orbital complexes involving d2sp3
hybridisation,on the other hand, [MnCl6]3– is outer orbital complexes involving sp3d2 hybridisation.
Assertion (A): For strong electrolytes, there is a slow increase in molar
conductivity with dilution and can be represented by the equation
Reason (R): The value of the constant ‘A’ for NaCl, CaCl2, and MgSO4 in a
given solvent and at a given temperature is different.
Assertion (A) Glucose does not form the hydrogensulphite addition product
with NaHSO3 .
Reason (R): Glucose exists in a six-membered cyclic structure called pyranose structure.

Assertion (A): The half- life for a zero order reaction is independent of the initial
concentration of the reactant.
Reason (R): For a zero order reaction, Rate = k
