Question

1- Hexane has the following molecular formula C6H14.

1.1- Prove that it belongs to alkanes family.

1.2- Write its structural formula.

1.3- Write the condensed structural formulas of its isomers and name them.

1.4- Arrange the boiling points of the different isomers in increasing order and justify your answer.

Answer 1

1.1. Alkanes have formula C_xH_2x+2. (6 × 2) + 2 = 14 $\implies$ hexane is alkane.

1.2.-1.3. on the picture

1.4. 4<5<3<2<1: the more symmetric and branchd alkane is, the lower its boiling point.
