Question

Write down any two methods of preparation of Alkanes along with two chemical properties.

Answer 1

Answer:decarboxylation

For methane and ethane

Reaction with iodomethane to get methane

And reaction with bromoethane to get ethane

Explanation:

CH3COONa+ NaOH in the presence of CaO gives you CH4 + Na2CO3

CH3I + [H] gives CH4 + HI

Alkanes are saturated hydrocarbons

Alkanes have single bonds

Alkanes undergo substitution reaction and combustion

Answer 2

Answer:

CH3cCH3CONaOH presence of CaO gives CH4+Na2CO3
