Write chemical equations for combustion reaction of the following hydrocarbons:
(i) Butane
(ii) Pentene
(iii) Hexyne
(iv) Toluene

Explanation

(i) `underset("Butane")(C_(4)H_(10)(g)) +(13)/(2)O_(2)(g) to 4CO_(2)g(g) + 5H_(2)O(g)`
(ii) `underset("Penene")(C_(5)H_(10)(g))+(15)/(2)O_(2)(g) to 5CO_(2)(g) + 5H_(2)O(g)`
(iii) `underset("Hexyne")(C_(6)H_(10)(g))+(17)/(2)O_(2)(g) to 6CO_(2)(g) +5H_(2)O(g)`
(iv) `underset("Toluene")(C_(7)H_(8)(g))+9O_(2)(g) to 7CO_(2)(g) + 4H_(2)O(g)`
