Buna –S: It is also known as styrene-butadiene rubber (SBR). For double bond ‘ene’ suffix is used. Its empirical formula is, Assume a 100g sample, convert the same % values to grams, Moles of Hydrogen = 13.33g / [1g/mol] = 13.33 mol, Moles of Nitrogen = 46.67g / [14g/mol] = 3.33 mol, After dividing the smallest resultant mole by each atom, C = 3.33 / 3.33 = 1; H = 3.33 / 13.33 = 4; N = 3.33 / 3.33 = 1. So, optical activity is not a colligative property. From Ist order kinetic equation t1/2 = (2.303 / k) log {a / (a - [a / 2])}, Again from Ist order kinetic equation t = (2.303 / k) log (a / [a - x]), = [240 min × 2.303 × log 2] / [60 × 2.303], If initial concentration (a) taken as 100%, Then, % of the reactant left after 240 min = 100 / [a - x] = 16. If the concentration of −OH ion is decreased by ¼ times. The Nitro group is an electron-withdrawing in nature.
