Question

Which compound matches the IR Spectrum?
A) 1, 5 – hexadiene
B) 3 – Hexanol
C) Trans – 4 – octene
D) None of the above

Answer 1

A) 1, 5 – hexadieneB) 3 – HexanolC) Trans – 4 – octeneD) None of the above

Answer:   A) 1, 5 – hexadiene 

Explanation:

3 – Hexanol:

There is no alcohol stretch present in the spectrum. Therefore, the above structure is not suitable for the given spectrum.

Trans – 4 – octene:

There is no vinyl bending present in the spectrum. Therefore, the above structure is not suitable for the given spectrum.

1, 5 – hexadiene:

The vinyl bending and other stretches were matched with the above structure.

Hence, the c = c stretch, vinyl bending andstretch were matched with the above structure

Therefore, the given spectrum belongs to 1, 5 – hexadiene.

Answer 2

The answer is :-

A] 1,5 - hexadiene
