Structural formua of the product formed when each alkene is treated with one equivalent of NBS in C H 2 C l 2 in presence of light has to be drawn. Concept introduction: Bromine does not act as good source for free radical bromination on allylic C-H bonds since it will simply add to the alkene. • NBS: N-bromosuccinimide: using NBS with low concentration of Bromine molecule, that catalyzed by HBr leads to th eproduct. • Allylic susbstitution using NBS involves a net double substitution i.e, B r in NBs is exchanged by the hydrogen in alkene.

Question

How many milliliters of 97.5(±0.5) wt% H2SO4 with a density of 1.84(±0.01) g/mL will you need to prepare 2.000 L of 0.110 M H2SO4? If the uncertainty in delivering H2SO4 is ±0.01 mL, calculate the absolute uncertainty in the molarity (0.110 M). Assume there is negligible uncertainty in the formula mass of H2SO4 and in the final volume (2.000 L) and assume random error.
