Question

1. Write suitable equation to represent
a) sodalime de carboxylation​

Answer 1

Answer:

does NOT cover the decarboxylation of some acids by simply ... Decarboxylation using soda lime ... In equations, it is almost always written as if it were simply sodium ...

Answer 2

Decarboxylation reaction is used with Carboxylic acid salts to give alkanes.

Soda lime is a mixture of NaOH and Ca(OH)2.

Examples:

1) Sodium Ethanoate Decarboxylation:

                                      Ca(OH)2

CH3COONa + NaOH --------------->   Na2CO3 + CH4 (methane-alkane)

                                          △

2) Sodium propanoate Decarboxylation:

                                            Ca(OH)2

CH3CH2COONa + NaOH --------------->   Na2CO3 + C2H6 (ethane-alkane)
