Select the incorrect statement regarding the boiling points of alkanes. a) Boiling point increases with stronger Vander Waal’s forces b) Surface area is the only factor which determines the boiling point of alkane c) Boiling point of straight chain alkanes is greater than that of branched chain alkanes
WebTherefore, all alkanes are insoluble in polar solvents such as water, as like-dissolves-like. Rather liquid alkanes can be used as non-polar solvents themselves. You must note that a straight-chain alkane is always more stable with higher melting and boiling points than a branched alkane molecule with the same number of C-atoms. WebJul 30, 2024 · alkanes, n-butane has a lower boiling point than n-pentane. This model seems to work well with n-alkanes, because increases in molecular weight are highly correlated to the
