Expert Solution
Step 1

To find:

the correct specturm and match the structure and to give the reason:

 

Step 2

Explanation:

(a)  spectrum belongs to cyclohexanone.

                                    Chemistry homework question answer, step 2, image 1

the strong absorption at 2941 cm-1 represents the alkane C-H bond and 1717 cm-1represents the C=O bond in the cyclohexanone.

 

Step 3

(b) This spectrum belongs to butan-1-ol.

 

Chemistry homework question answer, step 3, image 1

the very broad absorption in 3333cm-1 corresponds to the hydrogen bond in the alcohol group and 1466cm-1 represents the C-H bending.

Step 4

(c) this spectrum belongs to cyclohex-2-en-1-one.

Chemistry homework question answer, step 4, image 1

the broad absorption in 3341cm-1is due to the alcohol group, 3026cm-1 represents the hydrogen that is attached to the ring, 1650 cm-1 is due to the alkene group in the ring, 1450cm-1 represent the aromatic ring.
