Answer 1

Chemical properties of Alkanes

Some of the major chemical properties of alkanes are as follows:

1. Alkanes show a general chemical formula of CnH2n+2.
2. Alkanes are less reactive than the other chemical molecules. This is because the C-C and C-H bonds in the alkane molecules are sigma bonds, which are extremely stable.
3. Alkanes show a higher density than water.
4. The alkanes are non-polar in nature as they mainly consist of C and H atoms. They are immiscible in the polar solvents, however they can easily mix in the non-polar solvents
5. Alkanes do not easily react with polar and ionic molecules. They show a pKa value more than 50, which makes them inert to a majority of the bases and acids.
6. Alkanes undergo redox reactions. They undergo oxidation reactions to yield aldehydes, alcohols and other such substances. On the other hand, alkanes undergo substitution reaction to yield halogenated compounds. They also form bonds with various transition metal complexes.

Answer 2

Top 5 chemical characteristics of alkanes are as follows.

Explanation:

• Alkanes are the compounds of carbon and hydrogen.

• These compounds are highly apolar.

• They aren't soluble in any polar solvent.

• They aren't acidic with pKa value more than 50.

• They prefer substitution reaction than addition reaction.

• As electronegativity of hydrogen and carbon are quite closer, so they prefer free radicle reactions.
