Which structure is heptane?
A straight-chain alkane with seven carbon atoms. It has been found in Jeffrey pine (Pinus jeffreyi). Heptane or n-heptane is the straight-chain alkane with the chemical formula H3C(CH2)5CH3 or C7H16, and is one of the main components of gasoline (petrol).
What intermolecular forces does heptane have?
Pentane, hexane and heptane differ only in the length of their carbon chain, and have the same type of intermolecular forces, namely London dispersion forces. London forces increase with molecular size (number of electrons in a molecule).
What are isomers of butane?
It has two isomers; n-butane and isobutane.
- Here n-butane is a straight-chain compound with four carbon atoms bonded with single covalent bonds.
- Another isomer is isobutane or 2-methylpropane in which three carbon atoms from the parent chain and one carbon atom is placed as the side chain at C-2 of the parent chain.
