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

Explanation

`(i)underset"Butane"(C_4H_10 (g)) + 13//2 O_2(g) oversetDelta to 4CO_2(g) + 5H_2O (g)`
`(ii)underset"Pentene"(C_5H_10 (g)) + 15//2 O_2(g) oversetDelta to 5CO_2(g) + 5H_2O (g)`
`(iii)underset"Hexyne"(C_4H_10 (g)) + 17//2 O_2(g) oversetDelta to 6CO_2(g) + 5H_2O (g)`
(iv)
