Question

write combustion reaction for hexyne​

Answer 1

hexyne is has 6 Carbon atoms in CnH2n-2.

So, it is C6H10

Combustion means reaction with oxygen.

C6H10 + O2 --> CO2 + H2O (Hydrocarbon + Oxygen = Carbon dioxide + Water)

Balancing...

C6H10 + 8(1/2)O2 --> 6CO2 + 5H2O

Answer 2

The formula of hexyne = C6H10

general reaction for combustion of a hydrocarbon-

CxHy + (x+y/4)O2 =>xCO2 + (y/2)H2O

so the balanced chemical equation for the combustion of hexyne is

C6H10 + (6+10/4)O2 => 6CO2 + 5H2O

C6H10 +(17/2)O2 => 6CO2 + 5H20
