| Re: WBJEE Sample Question Papers
West Bengal Joint Entrance Exam Model Papers provide much help in preparation in the Examination. Some of the questions are given below. Sample Questions: Which one of the following is the correct statement? i. Chlorides of both beryllium and aluminium have bridged chloride structures in solid phase. ii. B2H6.2NH3 is known as 'inorganic benzene'. iii. Boric acid is a protonic acid. iv. Beryllium exhibits coordination number of six. The pKa of a weak acid, HA is 4.80. The pKb of a weak base, BOH, is 4.78. The pH of an aqueous solution of the corresponding salt, BA, will be i. 7.01 ii. 9.22 iii. 9.58 iv. 4.79 Amount of oxalic acid present in a solution can be determined by its titration with KMnO4solution in the presence of H2SO4. The titration gives unsatisfactory result when carried out in the presence of HCl, because HCl i. reduces permanganate to Mn2+. ii. oxidises oxalic acid to carbon dioxide and water. iii. gets oxidised by oxalic acid to chlorine. iv. furnishes H+ ions in addition to those from oxalic acid. Among the following substituted silanes the one which will give rise to cross linked silicone polymer on hydrolysis is i. R2SiCl2 ii. R3SiCl iii. R4Si iv. RSiCl3 Which of the following factors is of no significance for roasting sulphide ores to the oxides and not subjecting the sulphide ores to carbon reduction directly? i. Metal sulphides are less stable than the corresponding oxides. ii. CO2is more volatile than CS2. iii. Metal sulphides are thermodynamically more stable than CS2. iv. CO2is thermodynamically more stable than CS2.    Here I am attaching the Sample Question Papers of WBJEE Examination:

This is the WBJEE Mathematics Previous years question paper: Eleven apples are distributed among a girl and a boy. Then which one of the following statements is true ? (A) At least one of them will receive 7 apples (B) The girl receives at least 4 apples or the boy receives at least 9 apples (C) The girl receives at least 5 apples or the boy receives at least 8 apples (D) The girl receives at least 4 apples or the boy receives at least 8 apples Ans : () If a, b, c are in A.P., then the straight line ax + 2by + c = 0 will always pass through a fixed point whose co-ordinates are (A) (1, –1) (B) (–1, 1) (C) (1, –2) (D) (–2, 1) Ans : (A) In the set of all 3×3 real matrices a relation is defined as follows. A matrix A is related to a matrix B if and only if there is a non-singular 3×3 matrix P such that B = P–1AP. This relation is (A) Reflexive, Symmetric but not Transitive (B) Reflexive, Transitive but not Symmetric (C) Symmetric, Transitive but not Reflexive (D) an Equivalence relation Ans : (D) For any two real numbers a and b, we define a R b if and only if sin2 a + cos2b = 1.
