Q: What happens when alkanes are mixed with oxygen at room temperature?


Read this paragraph and choose the correct option from the provided answers:

Neither positive ions nor negative ions are attracted to a nonpolar molecule. In fact, the alkanes undergo so few reactions that they are sometimes called paraffins, from the Latin parum affinis, meaning “little affinity. ” Two important reactions that the alkanes do undergo are combustion and halogenation. Nothing happens when alkanes are merely mixed with oxygen (O2) at room temperature, but when a flame or spark provides the activation energy, a highly exothermic combustion reaction proceeds vigorously. For methane (CH4), the reaction is as follows:.

 Choices:

- single replacement

- redox

- combustion

- no reaction


A:
no reaction
