Write IUPAC names of the products obtained by addition reactions of HBr to hex-1-ene: i) In the absence of peroxide

Welto IUPAC names of the products obtained by addition reactions of HBr to hex-1-ene: In the absence of peroxide.

Consider the following metallurgical processes in 1. Heating impure metal with CO and distilling the resulting volatile carbonyl boiling point 43^@C and finally decomposing at 150^@ to 200^@C to get the pure metal. II. Heating the sulphide ore in air until a part is converted to oxide and then further heating in the absence of air to let the oxide react with unchanged sulphide. III. Electrolysing the molten electrolyte containing approximately equal amounts of the metal chloride and CaCl_2 to obtain the metal. The processes used for obtaining sodium, nickel and copper are respectively

One of the steps in metallurgy is concentration of ores majority of theconcentration techniques are physical in nature _____is the process of heating the concentrated ore strongly in the absence of air.

A polystyrene, having the formula Br_(3)C_(6)H_(3)(C_(3)H_(8))_(n) , was prepared by heating styrene with tribromobenzoyl peroxide in the absence of air. If it was found to contain 10.46% bromine by weight, find the value of n.
