Re: GATE Chemistry Previous Year solved Question Papers
Here I am giving you question paper for chemistry subject in GATE examination in a PDF file attached with it so you can get It easily. Q.1 In the proton decoupled 13C NMR spectrum of 7-norbornanone, the number of signals obtained is (A) 7 (B) 3 (C) 4 (D) 5 Q.2 Identify the most probable product in the given reaction (A) (B) (C) (D) Q.3 In the cyclization reaction given below, the most probable product formed is (A) (B) (C) (D) Q.4 If Δy and Δpy are the uncertainties in the y-coordinate and the y component of the momentum of a particle respectively, then, according to uncertainty principle ΔyΔpy is ( 2 h and h is Planck’s constant) (A) (B) > 2 (C) > (D) 2 Q.5 The average length of a typical α-helix comprised of 10 amino acids is (A) 10 Å (B) 15 Å (C) 36 Å (D) 54 Å Q.6 Number of thymine residues in a 5000 kb DNA containing 23% guanine residues is (A) 2.70 × 106 (B) 2.70 × 107 (C) 1.35 × 106 (D) 1.35 × 107 Q.7 Shown below is a Hammett plot obtained for the reaction The change in slope of the plot indicates that (A) the reaction does not follow linear free energy relationship (B) electrons are being withdrawn from the transition state in the mechanism (C) electrons are being donated to the transition state in the mechanism (D) the mechanism of the reaction is changing Q.8 The ratio of relative intensities of the two molecular ion peaks of methyl bromide (CH3Br) in the mass spectrum is (A) M+ : (M+2)+ = 1:3 (B) M+ : (M+2)+ = 3:1 (C) M+ : (M+2)+ = 1:1 (D) M+ : (M+2)+ = 1:2 |
