Why Isodecane (B.P.: 327 *C) has a higher boiling point than decane (B.P.: 174.1 *C)? Branched chain molecules have lower boiling point than straight chain molecules because branched chain molecules have a smaller surface area where they can be attracted by other molecules. Then, why Isodecane (a branched chain molecule) has a higher boiling point than Decane (a straight chain molecule)?
The only problem here is the units - the boiling point of isodecane is given in Fahrenheit and the boiling point of decane in Celsius.
