In chemistry a convergent synthesis is a strategy that aims to improve the efficiency of multi-step chemical synthesis. In linear synthesis the overall yield quickly drops with each reaction step: A → B → C → D Suppose the yield is 50% for each reaction, the overall yield of D is only 12.5% from A. In a convergent synthesis A → B (50%) C → D (50%) B + D → E (25%) the overall yield of E (25%) looks much better. Convergent synthesis is applied in the total synthesis of complex molecules and involve fragment coupling and independent synthesis. Example:
- Convergent synthesis is encountered in dendrimer synthesis where branches (with the number of generations preset) are connected to the central core
- Proteins of up to 300 amino acids are produced by a convergent approach using chemical ligation.

What is the difference between a convergent and divergent series?
A convergent series is a series whose terms approach a finite limit as the number of terms approaches infinity. In other words, the sum of the terms in a convergent series approaches a finite value. On the other hand, a divergent series is a series whose terms do not approach a finite limit as the number of terms approaches infinity. The sum of the terms in a divergent series does not converge to a finite value.
What is a sequence which is not convergent defined as?
It could be divergent eg 1+1+1+1+... Or, it could be oscillating eg 1-1+1-1+ ... So there is no definition for a sequence that is not convergent except non-convergent.
What is a real word example of convergent?

What is a verb for approach?
