sulphuric acid is a stong enough oxidising agent so a concentrated sulphuric acid couldn't be used because it will further get reduced it self and will oxidise the halide ion to form iodine or bromine resulting in now HI or HBr for the reaction with alcohol to form haloalakane.

You guys are wrong.
You see, the Bromine and Iodine ions are very powerful reducing agennts compared to that of Chlorine, and would result in further reactions, that would not form other products. http://www.chemguide.co.uk/inorganic/group7/halideions.html#top. This site will help u understand the whole thing.

lol mysterious i said the same thing but in the opposite way i said sulpuric acid is a strong oxidising agen (poor reducing agent) and bromine ions and iodide ions they get oxidised which means that they are poor oxidising agents and strong reducing agents
it doesn't matter in what way you put because they both stands for the same answer but the problem is you shouldn't mix up when writing which one is the oxidising and which one is the reducing agent
