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 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?
Coming together.
What is a verb for approach?
approach
How many syllables are in the word synthetic?
The word synthetic has three syllables. Syn-thet-ic.
Any convergent sequence is a Cauchy sequence is converse true?
no converse is not true
What is convergent research?
When two or more lines of research begin to converge on a similar result this is referred to as convergent evidence. Convergent research is the designed use of more than one theoretical approach to examine a problem space.
What is the movement of the convergent boundary?
A convergant boundary is destructive because the plates approach one another.
What is convergent research in bilingual education?
Convergent research, in any forum, is basically when research from at least two very different venues (or processes) comes to the same basic conclusion. "When two or more lines of What_is_convergent_researchbegin to converge on a similar result this is referred to as convergent evidence. Convergent research is the designed use of more than one theoretical approach to examine a problem space."Read more: What_is_convergent_researchSo therefore, convergent research in bilingual education would likely be the similar result that is the product of two or more different lines of bilingual education research.
What are the types of convergent boundary?
There are 3 types of Convergent boundaries, they are; 1. Continental-continental convergent boundary. 2. Continental-oceanic convergent boundary. 3. Oceanic-oceanic convergent boundary.
Why are convergent plate boundary's called convergent?
At convergent boundaries plates come together. In other words, they converge.
Is lithosphere sinking into the mantle divergent convergent or transform?
Convergent.
A convergent boundary causes what stress type?
A convergent boundary causes compressional stress.
What are the types of convergence?

Is Mount Vesuvius near a hot spot divergent or convergent plate boundary?
Vesuvius is associated with a convergent boundary between the African Plate and the Eurasian Plate.
What has the author R D Thomas written?
R. D. Thomas has written: 'An organoiron approach to Dihydrodioscorine' 'Synthetic studies using quinones and related compounds'
What type of boundary form a volcanic mountain range near a coastline?
They form on convergent boundaries.
What is the name of the boundary where two plates are moving toward one another?
Convergent boundary.
