How does branching affect stability
WebThe position of the branching also has an effect on steric hindrance.The closer the methyl group is to the carboxyl, the more steric hindrance should be.This should be reflected in a lower boiling point. (For comparison, ketones will be used.Boiling points of branched C7H14O aldehydes were difficult to locate. WebMay 8, 2024 · $\begingroup$ Okay, so for the melting point, we have three different effects : 1) The molecule becomes more sphere-like, so the surface area decreases, and the strength of the Van Der Waals forces decrease. 2) The length of each chain becomes longer, so the Van Der Waals forces increase. 3)In general, branching decreases the symmetry of the …
