Answer:

Scientific method.

Explanation:

Scientific method is the way taken to acquire scientific knowledge. It includes experiments, statistical analysis of existing data, and all kinds of observations of the world around us, while theoretical research is based on deriving certain theories about the world from basic principles, in a mathematical or logical way. The scientific method applies to both types of research, and emphasizes that scientific research is objective, that it can be verified by other scientists, and that knowledge is not acquired without context, but in a way that leads to a greater understanding of previous research and the world. we live in. To contribute to this, researchers are expected to clearly record both their findings and the methods they use to arrive at the results.

puteri [66]

Answer:

  1. Elimination
  2. Elimination
  3. Zaitsev
  4. Zaitsev
  5. Carbocation

Explanation:

  • The mechanism is generally accepted to always operate via an ELIMINATION step-wise process.
  • The ELIMINATION mechanism process will always produce (after dehydration) a ZAITSEV style alkene as major product
  • The driving force for the production of this ZAITSEV style alkene product is generally going to be determined by stability of the CARBOCATION

Elimination mechanism is the removal of two substituents  from a molecule in either a one- or two-step mechanism

Carbocation is a molecule containing a positive charged carbon atom and three bonds
