Answer true or false. (a) Boiling points among alkanes with unbranched chains increase as the number

Answer true or false.

 (a) Boiling points among alkanes with unbranched chains
increase as the number of carbons in the chain increases.

(b) Alkanes that are liquid at room temperature are more
dense than water.

(c) Cis and trans isomers have the same molecular formula,
the same connectivity, and the same physical properties.

 (d) Among alkane constitutional isomers, the least branched
isomer generally has the lowest boiling point.

 (e) Alkanes and cycloalkanes are insoluble in water. (f)
Liquid alkanes are soluble in each other.
