How is iodination of alkane shifted in the forward direction?
Iodination is extremely slow and reversible in nature.
HI is a strong reducing agent and converts methyl iodide back to methane. In order to carry out the reaction in the forward direction. HI is destroyed with the help of an oxidising agent like iodic acid (HIO3), concentrated. HNO3 or mercuric oxide (HgO).
Name the metal which is a constituent of Grignard's reagent.
Name the products formed when an ethereal solution containing ethyl iodide and methyl iodide is heated with sodium metal.
Alkanes are less reactive. Why?
Out of n-pentane, isopentane and neopentane which has lower boiling point?
During the pyrolysis of alkanes C-C bonds break in preference to C-H bond. Why?
Define cracking.
What is the function of iodic acid in the iodination of alkanes? Can we use any other substance in its place?
What is alternation effect?
Arrange the following compounds in order of their increasing boiling points:
n-Pentane, n-Hexane, Ethane, 2-2-Dimethylpentane, 2-Methylpentane.
Why is light or heat necessary to initiate chlorination reaction of alkanes?
