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.

What happens to a population of predators, perhaps a pride of lions, if their prey, say the gazelle population, in their area wa
lys-0071 [83]

Explanation:

1. Since the Lions are the predator and Gazelles are the prey therefore a predator-prey relationship exists between them. The predator-prey relation is also associated with the food chain in an ecosystem. If the number of prey is reduced then there are chances that the number of a predator will also be reduced but

2. The Lion is not just the predator of Gazelle but other animals also like deer therefore they can shift their resource of food from gazelles to another organism.

3.The change of the ecosystem will change the population of the predator as the population are adapted to grow in a particular ecosystem and change of population could reduce the population of a predator.
