Is the oxygen derivative of the hydrocarbon a non-methane total hydrocarbon?
Since it is a hydrocarbon, it is bound to be a hydrocarbon, and the oxygen derivative of the hydrocarbon is not a hydrocarbon! Therefore, even if the oxygen-containing derivative is volatile again, it is not a non-methane total hydrocarbon
What is the total hydrocarbon for non-methane? Non-methane total hydrocarbons generally refer to all volatile hydrocarbons other than methane (which are predominantly C2 to C8), abbreviated NMHC
Hydrocarbon derivatives of hydrocarbons do not belong to non-methane total hydrocarbons
