1. A liquid compound gave a mass spectrum showing a strong molecular ion at m/z = 156. The only fragment ions are seen at m/z = 127 and 29. Suggest a structure of this compound. 2. A liquid compound gave a mass spectrum in which the molecular ion appears as a pair of equal intensity peaks at m/e = 122 and m/z = 124. Small fragment ion peaks are seen at m/z = 107 and 109 (equal intensity) and at m/z = 79, 80, 81 and 82 (all roughly the same size). Large fragment ions are seen at m/z = 43 (base peak), 41 and 39. Suggest a name for this compound. I suppose the first one would be C11H24 (MW = 156) which breaks down into ionic fragments C2H5+ (MW = 29) and C9H19+ (MW = 127). Am I correct? And I am totally clueless about the second question. Any guidance would be appreciated. Thanks.
