Explanation / Answer
Answer – We are given the IR spectrum of the compound drawn and need to find out the statements is (are) true about the IR spectrum –
In the given compound there is cyanide, carbonyl and alkyl halide functional group are presents, so we are there are IR spectrum range between the
-2210-2260 for the cyanide
-1705-1725 cm-1 for th carbonyl group
-500-600 cm-1 for the C-Br stretching.
There are IR spectrum between 2850-3000 cm-1
So there is - Both statements (It shows absorptions at 3000-2850 cm-1 and 2150 cm-1) and (It shows absorptions at 2150 cm-1 and 1720 cm-1) are true.
