In what way does a solution of hydrogen peroxide react with (a) chlorine water, (b) potassium permanganate solution, (c) potassium dichromate solution, (d) hydrogen sulphide 50 cm of an aqueous solution of hydrogen peroxide were treated with an excess of potassium iodide and dilute sulphuric acid the liberated iodine was titrated with 0.1 M sodium thiosulphate solution and 20.0 cm were required. Calculate the concentration of the hydrogen peroxide solution in g 1" ... 

The most interesting and difficult cross-coupling is alkyl-alkyl coupling, because oxidative addition of alkyl halides having /i-hydrogen is slow. In addition, easy elimination of /d-hydrogen is expected after the oxidative addition. 

Oscine, CgHiaOjN, This substance, for which the name scopolin is in use in continental Europe, was first examined by Hesse and later t Luboldt. It forms colourless, hygroscopic prismatic crystals, m.p. 109 from ether or light petroleum, and boils at 241-3°. cZZ-Oscine has bee resolved into the d- and Z-forms by King by crystallisation of tl d-hydrogen tartrates. The characters of the three forms of oscine and ( their picrates and hydrochlorides are tabulated on p. 87. 

Hoshino and Kobayashi (1933) have also described the resolution of di-eserethole by crystallising the mixed d-hydrogen tartrates from alcohol, when d-eserethole d-hydrogen tartrate [m.p. 173-4°, [a]D ° + 113° (HgO) ] separated first. The base recovered from the mother liquors yielded with 1-tartaric acid, l-ha.se i-hydrogen tartrate (m.p. 173-4°, [ajj, — 113°). The active picrates had m.p. 133-6° and the di-picrate m.p. 132°.
