Question

Which reaction below requires the greatest amount of amount of oxygen per mole of explosive for complete oxidation (combustion) to CO2 and H2O.

a. CH3OH
b.CH2=CHCH3
c. CH Ξ CH
d. No right answer.

Answer 1

The answer to your question is: letter B

Step-by-step explanation:

First, write the reactions and balance them

a. 2 CH3OH + 3 O2 ⇒ 2 CO2 + 4 H2O

ratio 3/2 = 1.5

b. 2 CH2 = CHCH3 + 9 O2 ⇒ 3 CO2 + 3 H2O

ratio 9/2 = 4.5

c. 2 CH ≡ CH + 5 O2 ⇒ 4 CO2 + 2 H2O

ratio 5/2 = 2.5
