- All alkanes have low B.P and are non-polar due to non-polar covalent bonds. Alkanes have weak London forces. According to 2nd factor B.P of alkanes gradually increases with the number of # C atoms.
- All alkanes are insoluble in water due to non-polarity.
- Alkanes of
Preparations
1. Chlemenson Reduction (Aldehyde/Ketone)
- Formaldehyde gives methane.
- This reaction can be used to attach 2D or 2H atoms.
- Instead of c.HCl, if c. DCl is used it can obtain 2D (Deuterium) atoms.
- 2D atoms in a molecule shows it has undergone Chlemenson reduction.
2. Catalytic Hydrogenation (Alkenes/Alkynes)
