The number of alkanes having n carbons and a longest chain of length d: an application of a theorem of Polya This paper tackles the problem of determining the number of structural isomers of an alkane. The primitive algorithm that is usually taught to students is ... AT Balaban,JW Kennedy...
To determine which isomer of pentane has the lowest boiling point, we first need to identify the isomers of pentane and then analyze their structures.1. Identify the Isomers of Pentane: - Pentane has the molecular formula \(

A related tricyclic intermediate IV has been characterized for reactions of bicyclo[1.1.0]butanes with Pt(II) complexes. Experimental observations also indicate that IV may be in equilibrium with its isomers formed by insertion of the metal into the lateral bonds of BCB II35,36. Alternatively, ...
2.4. X-ray analysis of 5 Single crystals of 5·C5H12 were grown by slow diffusion of pentane into a concentrated CH2Cl2 solution of 5, and the crystal structure was determined. Crystal data and refinement details are summarized in Table 1 and selected bond distances and angles are collected ...
The major disadvantages with the above prior-art process are the formation of mixture of isomers such as ethyl (E)-5-(tritylthio)pent-3-enoate (X) and ethyl (E)-5-(tritylthio)pent-2-enoate (Xa); and (E)-5-(tritylthio)pent-3-enal (XI) & (E)-5-(tritylthio)pent-2-enal (XIa...
Hereby, we report that isotopic isomers are differently represented in the honeybee antennal lobe, supporting behavioural experiments showing that fruit flies and honeybees can discriminate isotopomers of the same odorant9,11. Also, we wish to underline that the majority of the glomeruli responded in...
