Question

write combustion reaction for hexyne

Answer 1

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    answer

Answer 2

Hexyne is an alkyne and
Alkyne has the general formula
CnH2n-2
where is the number of atoms of the molecule.
Combustion of hexyne yield Water H2O and Carbon dioxide CO2.
Hexyne has the general formula C6H10 its combustion reaction will be
C6H10+17/2O2-----> 6CO2+5H2O
