What is alternation effect?
n-alkanes with an even number of carbon atoms have much higher melting points than the next lower n-alkane with an odd number of carbon atoms.
During the pyrolysis of alkanes C-C bonds break in preference to C-H bond. Why?
The bond dissociation energy of C-C bond is less than that of C-H bond. Hence, C-C bonds break in preference to C-H bond.
What is the function of iodic acid in the iodination of alkanes? Can we use any other substance in its place?
Arrange the following compounds in order of their increasing boiling points:
n-Pentane, n-Hexane, Ethane, 2-2-Dimethylpentane, 2-Methylpentane.
