Question

write the structure and IUPAc name of the structural isomers with molecular formula C3H6.Which one of the isomers can't be a homologue of the unsaturated hydrocarbon series?How can the isomers be distinguished by a simple chemical test?please answer these questions for me!

Answer 1

iupac name is propene. isomers of carbon compound starts from the compound having four carbon atoms so propene has no isomers

Answer 2

Ans:

i) IUPAC name is Propene.

Isomers of carbon compound starts from the compound having 4 carbon atoms so Propene will have no isomers.

ii) Combustion reaction:— Alkene burn with a luminous flame to give CO2 and H2O

CnH2n + 3n/2 O2……> nCO2 + nH2O

whereas alkyne burn in air with sooty flame

CnH2n—2 + ( 3n—1)/2 O2 ……..> nCO2 + (n—1) H2O
