Answer true or false. Boiling points among alkanes with unbranched chains increase as the number of carbons in the chain increases. Alkanes that are Equid at room temperature are more dense than water. Cis and trans isomers have the same molecular formula, the same connectivity, and the same physical properties. Among alkane constitutional isomers, the least branched isomer generally has the lowest boiling point. Alkanes and cycloalkanes are insoluble in water. Liquid alkanes are soluble in each other.
