Construct a three-step synthesis of trans-2-pentene from acetylene by dragging the appropriate formulas into the bins. Note that
lozanna [386]

Answer:

A. Production of higher order terminal alkyne on reaction with sodium acetylides with haloalkane.

B. It includes the further alkylation of terminal alkynes to higher order nonterminal alkynes and

C. The production of trans-pent-2-ene by the use of the dissolving reduction method.

Explanation:

Concepts and reason

The basic idea of this case study is on the conversion of an alkyne to an alkene. Alkynes are unsaturated and can go through addition reactions. The essential chemical processes of alkynes involves the electrophilic addition reactions, nucleophilic addition reactions , reactions as a result of acetylenic hydrogen, polymerisation, isomerization and oxidation reactions.

Fundamentals

The conversion of an alkyne to alkene involves two basic processes which as to do with the production of higher alkynes from lower alkynes with the next phase involving the dissolved metal reduction of the higher order alkyne so as to form an alkene.

Conversion of acetylene (ethyne) to one higher order alkyne as shown in the first attached image.

Terminal alkynes combine with sodamide to produce acetylides that reacts with the haloalkanes (In this case, we using methyl bromide) to form higher order alkynes.

The reaction is as well represented in the second attached image.

Alkylation of terminal alkyne leads to the production of higher nonterminal alkyne (which is propyne) that is converted to higher order nonterminal Pent-2-yne.

The reaction is shown in the third attached image.

The entire or total hydrogenation of alkynes produces a corresponding alkane by passing hydrogen in the presence of metal catalysts. Partial hydrogenation of alkynes could lead to the development of cis- or trans- alkenes which is reliant on the reagent employed.

The right reagents and products in the total reaction is duly represented in the fourth attached image.

The Synthesis of trans-pent-2-yne from ethyne involves basically a three-step synthesis which includes

A. Production of higher order terminal alkyne on reaction with sodium acetylides with haloalkane.

B. It includes the further alkylation of terminal alkynes to higher order nonterminal alkynes and

C. The production of trans-pent-2-ene by the use of the dissolving reduction method.

• The last attached image has the answers being put in the adequate bin.

in the adult digestive tract, where do lipases break fat into fragments so that it can be absorbed into the lymph?
Strike441 [17]

As to the digestive tract, the function of the lipases would take place in the small intestine.

Lipase is an enzyme that helps us to <u>metabolize fat</u>. It does this through <u>hydrolysis</u>. Although in reality, as an enzyme, its main function is to catalyze this process. Lipases are the subclass enzyme of the esterases.

Lipases are necessary for the proper digestion and transport of fats in the form of lipids. They are also essential to process these lipids in the human body. This enzyme is present in most living organisms outside of humans.

Although lipase enzymes are produced throughout the body, the bulk of lipase production occurs in the pancreas. It will then travel to the small intestine to carry out its functions in the digestive tract.
