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.

Kidneys are often compared to filters because they cleanse unwanted waste from both frogs and humans true or false ?
PtichkaEL [24]

"Kidneys are often compared to filters because they cleanse unwanted waste from both frogs and humans" is TRUE.

Answer: Option A

<u>Explanation: </u>

Frogs also have the excretory system with two kidneys and similar to mammals. Its function is to eliminate the nitrogen product from the blood. Frogs make large volumes of dilute urine to wipe out harmful products from the tubules of the kidneys.

Tadpoles and aquatic frogs excrete the nitrogen as ammonia, but most terrestrial adults excrete it mostly as urea which is less threatening substance. A few tree frog species with little water access excrete the still less harmful uric acid.
