VMC IIT JEE Solutions

I want to Vidyamandir Classes (VMC) for the preparation of IIT JEE exam so is it best coaching centre for IIT JEE exam? provide me the contact phone number of the office of this Institute? Also provide me the directions to go to Vidyamandir Classes (VMC)?

Can you provide me previous year question paper of Joint Entrance Examination – Advanced (IIT-JEE) Paper-1 with solutions as I need it for preparation?

The previous year question paper of Joint Entrance Examination – Advanced (IIT-JEE) Paper-1 with solutions is as follows:


Calamine, malachite, magnetite and cryolite, respectively, are -
(1) ZnCO3, CuCO3, Fe2O3, Na3AlF6
(2) ZnSO4, CuCO3, Fe2O3, AlF3
(3) ZnSO4, Cu(OH)2, Fe3O4, Na3AlF6
(4) ZnCO3, CuCO3 ⋅ Cu(OH)2, Fe3O4, Na3AlF6
Ans. [4]


Which of the following statement(s) is (are) true?
(1) The two six-membered cyclic hemiacetal froms of D–(+)– glucose are called anomers
(2) Hydrolysis of sucrose gives dextrorotatory glucose and laevorotatory fructose
(3) Monosaccharides cannot be hydrolysed to give polyhydroxy aldehydes and ketones
(4) Oxidation of glucose with bromine water gives glutamic acid
Ans. [1, 2, 3]


An tin chloride Q undergoes the following reactions (not balanced)
Q + Cl– → X
Q + Me3N → Y
Q + CuCl2 → Z + CuCl
X is a monanion having pyramidal geometry. Both Y and Z are neutral compounds. Choose the correct options (s)
(1) The oxidation state of the central atom in Z is +2
(2) There is a coordinate bond in Y
(3) The central atom in Z has one lone pair of electrons
(4) The central atom in X is sp3 hybridized
Ans. [2, 4]


Fusion of MnO2 with KOH in presence of O2 produces a salt W. Alkaline solution of W upon electrolytic oxidation yields another salt X. The manganese containing ions present in W and X, respectively are Y and Z. Correct statement (s) is (are) -
(1) Both Y and Z are coloured and have tetrahedral shape
(2) Y is diamagnetic in nature while Z is paramagnetic
(3) In both Y and Z, π-bonding occurs between p-orbitals of oxygen and d-orbitals of manganese
(4) In aqueous acidic solution, Y undergoes disproportionation reaction to give Z and MnO2
Ans. [1,3,4]


Which of the following statement(s) is (are) correct regarding the root mean square speed (Urms) and average translational kinetic energy (εav) of a molecule in a gas at equilibrium ?
(1) εav is doubled when its temperature is increased four times
(2) εav at a given temperature does not depend on its molecular mass
(3) Urms is doubled when its temperature is increased four times
(4) Urms is inversely proportional to the square root of its molecular mass
Ans. [2, 3, 4]
