1. 2. The coordination number of an atom in a body-centred cubic structure is [Assume that the lattice is made up of atoms] Gaseous cyclobutene isomerizes to butadiene in a first order process which has 'k' value of 3.3 10-4 s at 153C. The time in minutes it takes for the isomerization to proceed 40% to completion at this temperature is (Rounded off the nearest integer) 3. The total number of amines among the following which can be synthesized by Gabriel synthesis is................... 4. H3C (A) H3C CH-CH2-NH2 (B) CH3CH2NH2 NH2 CH2 -NH2 (D) (C) Sucrose hydrolyses in acid solution into glucose and fructose following first order rate law with a half-life of 3.33 h at 25C. After 9h, the fraction of sucrose remaining is f. The value of log10 1 is.......... f .x 10-2. (Rounded off to the nearest integer) [Assume: In 10 = 2.303, In2 = 0.693]
