EAMCET is an entrance exam conducted by the Jawaharlal Nehru Technological University Hyderabad here I am giving you question paper for EAMCET examination in PDF file attached with it .. 31. Which one of the following statements is correct? (M-2002) 1) 2's' orbital is spherical with two nodal planes 2) The de Broglie wavelength ( λ ) of a particle of mass 'm' and velocity 'V' is equal to mV/h 3) The principal quantum number (n) indicates the shape of the orbital 4) The electronic configuration of phosphorous is given by [Ne] 3s2 3p1 x 3p1 y 3p1 z Ans: 4 Sol. Electronic configuration of p is [ ] 2 1 1 1 x y z Ne 3s 3p 3p 3p Alternate 4 is correct All other are wrong 32. Which one of the following ions exhibit highest magnetic moment? (E-2001) 1) Cu2+ 2) Ti3+ 3) Ni2+ 4) Mn2+ Ans: 4 Sol. [ ] 2 0 9 Cu Ar 4s 3d + = → 1 unpaired electron [ ] 3 0 1 Ti Ar 4s 3d + = → 1 unpaired electron [ ] 2 0 8 Ni Ar 4s 3d + = → 2 unpaired electrons [ ] 2 0 5 Mn Ar 4s 3d + = → 5 unpaired electrons Magnetic moment increases with increase in number of unpaired electron. 2 Mn + has more number of unpaired electron ∴ it has highest magnetic moment. 36. Which one of the following pairs of ions have the same electronic configuration? (M-2001) 1) Cr+3, Fe+3 2) Fe+3,Mn+2 3) Fe+3,CO+3 4) Sc+3,Cr+3 Ans: 2 Sol. [ ] 3 5 Fe Ar 3d + = [ ] 2 5 Mn Ar 3d + = 38. What are the values of n1 and n2 respectively for H β line in the Lyman series of hydrogen atomic spectrum? (E-2000) 1) 3 and 5 2) 2 and 3 3) 1 and 3 4) 2 and 4 Ans: 3 39. How many electrons are present in the M-shell of an atom of the element with atomic number Z=24? (E-2000) 1) 5 2) 6 3) 12 4) 13 Ans: 4 Sol. Z = 24 = 2 2 6 2 6 1 5 1s 2s 2p 3s 3p 4s 3d M shell = 3rd orbit ∴ In M shell 13 electron are present 40. The probability of finding an electron in an orbital is approximately? (M-2000) 1) 95% 2) 50% 3) 60% 4) 25% Ans: 1 Sol. The probability of finding an electron in an orbital is approximately 95%. 41. What is the wavelength of H β line the Balmer series of hydrogen spectrum? (R = Rydberg constant) (M-2000) 1) 36/5R 2) 5R/36 3) 3R/16 4) 16/3R EAMCET paper ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() EAMCET paper It is attached below please have a look on that
