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 naphthenes decreases with its increasing molecular weight & also on addition of double bond Smoking tendency of paraffins increases with decrease in its molecular weight 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 naphthenes decreases with its increasing molecular weight & also on addition of double bond Smoking tendency of paraffins increases with decrease in its molecular weight Smoking tendency of aromatics decreases with increase in its molecular weight ANSWER DOWNLOAD EXAMIANS APP
