Question

An organic compound absorbs strongly in the IR at 1687 cm^-1. On oxidation it is converted to benzoic acid. Its mass spectrum shows significant peaks at m/z 120, m/z 105 and m/z 77. This information is consistent with which of the following structures C-6H_5CH_2CH_2CH_3 C_6H-5CH(CH_3)_2 Select the structure of a compound C_6H_14 with a base peak at m/z 43. CH_3CH_2CH_2CH_2CH-2CH_3 (CH_3CH_2)_2CHCH_3 (CH_3)_3CCH_2CH_3 (CH_3)_2CHCH(CH_3)_2 None of these In ^13C NMR spectroscopy, the signal due to this type of carbon occurs furthest down field. -C equivalent N
