Question

Which of the following molecules has a characteristic stretch at 2200 cm -1 ?A)  (CH 3 )  2 CHCH 2 OHB)  (CH 3 )  3 CHC)  (CH 3 )  2 CHCCCH 3 D)  (CH 3 )  2 CHCH=CH 2 E)  (CH 3 )  2 CHCO 2 CH 3

Kristen Burlette · Accepted Answer

Final Answer : C, Explanation :  The characteristic stretch at 2200 cm-1 is due to a triple bond between two carbons. The only molecule among the choices that has a triple bond is choice C, which has a triple bond between the two end carbons of the molecule.
