Melting Point & Boiling Point - Detailed Explanation …

If the melting point of the mixture is 140oC then X is o-chlorobenzoic acid, but if the melting point is depressed by several degrees A and X cannot be identical. It is recommended that at least three minutes containing say 20 percent X +80 percent A:50 percent X+50 percent A; and 80 percent X+20 percent A be prepared and the melting point be determined.

Alkanes | Chemistry, Class 11, Hydrocarbons

24/4/2020· Alkanes with even nuer of carbon atoms have higher melting points than those with odd nuer of carbon atoms. The melting point of a substance depends not only upon the size and shape of the molecules but also upon how closely the molecules are packed in the crystal lattice, But due to sp 3 hybridization in alkanes, any two bonds of a carbon atom make an angle of 109°28′ with one another.
