Ethylene is used:
(i) for ripening citrus fruits,
(ii) as an anaesthetic,
(iii) for making ethylene glycol which is used as a coolant for air-craft engines and as antifreeze for motor cars.
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?
