  2. Structural isomer - Wikipedia

    en.wikipedia.org/wiki/Structural_isomer

    Functional isomers are structural isomers which have different functional groups, resulting in significantly different chemical and physical properties. [ 11 ] An example is the pair propanal H 3 C–CH 2 –C(=O)-H and acetone H 3 C–C(=O)–CH 3 : the first has a –C(=O)H functional group, which makes it an aldehyde , whereas the second has ...

  3. Isomer - Wikipedia

    en.wikipedia.org/wiki/Isomer

    Isomers do not necessarily share similar chemical or physical properties. Two main forms of isomerism are structural (or constitutional) isomerism, in which bonds between the atoms differ; and stereoisomerism or (spatial isomerism), in which the bonds are the same but the relative positions of the atoms differ. Isomeric relationships form a ...

  6. Heptadecane - Wikipedia

    en.wikipedia.org/wiki/Heptadecane

    The name may refer to any of 24894 theoretically possible structural isomers, or to a mixture thereof. The unbranched isomer is normal or n -heptadecane , CH 3 (CH 2 ) 15 CH 3 . In the IUPAC nomenclature, the name of this compound is simply heptadecane , since the other isomers are viewed and named as alkyl -substituted versions of smaller alkanes.

  8. Decane - Wikipedia

    en.wikipedia.org/wiki/Decane

    Decane is an alkane hydrocarbon with the chemical formula C 10 H 22.Although 75 structural isomers are possible for decane, the term usually refers to the normal-decane ("n-decane"), with the formula CH 3 (CH 2) 8 CH 3.

  9. Cis–trans isomerism - Wikipedia

    en.wikipedia.org/wiki/Cis–trans_isomerism

    The cis isomer in this case has a boiling point of 60.3 °C, while the trans isomer has a boiling point of 47.5 °C. [6] In the cis isomer the two polar C–Cl bond dipole moments combine to give an overall molecular dipole, so that there are intermolecular dipole–dipole forces (or Keesom forces), which add to the London dispersion forces and ...
