ISC - 2025 SPECIMEN PAPER - DETAILED DISCUSSION

There is a small mistake in question no. (4). There are two parts in this question and the second part is not answered. The answer for the second part will be as follows: No, propane cannot be prepared in pure state in this scheme because in that case a mixture of ethyl iodide and methyl iodide is required and in that case a mixture of three alkanes i.e. ethane, propane and n-butane will be obtained which are very difficult to separate and the yield of desired alkane i.e. will be very poor. Here I have tried to cover all the important points regarding the marking scheme so that you don't lose any marks in spite of knowing the correct answer. Will be glad if it becomes beneficial for the students. Comment if you have any further queries. I will try my best to answer.
