Petroleum Refinery Engineering Pick out the wrong statement about the smoking tendency of various hydrocarbon constituents of kerosene. Smoking tendency of hydrocarbons increases in the order : paraffins → isoparaffins → naphthenes → aromatics Smoking tendency of paraffins increases with decrease in its molecular weight Smoking tendency of naphthenes decreases with its increasing molecular weight & also on addition of double bond Smoking tendency of aromatics decreases with increase in its molecular weight Smoking tendency of hydrocarbons increases in the order : paraffins → isoparaffins → naphthenes → aromatics Smoking tendency of paraffins increases with decrease in its molecular weight Smoking tendency of naphthenes decreases with its increasing molecular weight & also on addition of double bond Smoking tendency of aromatics decreases with increase in its molecular weight ANSWER DOWNLOAD EXAMIANS APP
