Construct a three-step synthesis of trans-2-pentene from acetylene by dragging the appropriate formulas into the bins. Note that
adelina 88 [10]

Answer:

The three-step synthesis of trans-2-pentene from acetylene is as follows.

<u>Step -1:</u> Formation of higher order terminal alkyne on reaction with sodium acetylides with haloalkanes.

<u>Step -2:</u> Formation terminal alkyne to nonterminal alkynes.

<u>Step -3:</u> Formation of trans-pent - 2-pent-ene by reduction.

Explanation:

Synthesis of trans-pent-2-yne from ethyne takes place is mainly a three step synthesis which involves formation of higher order terminal alkyne on reaction with sodium acetylides with haloalkane. Second step involves the further alkylation of terminal alkynes to higher order nonterminal alkynes and the third step involves the formation of trans-2-ene by dissolving reduction method.

The chemical reaction of each step of chemical reactions is as follows.

An element's atomic mass does not include the mass of its <br> Electrons <br> Protons <br> Neutrons
klio [65]
  Mass  of  electrons  are not  included when  calculating  the  atomic  mass  of   element.  Atomic  mass  of  the   element  is  equal  to   proton  +  neurons.  Example  the    the  mass  number  of  Nitrogen can   be  calculated as      7 protons  +  7  neutrons  to  give 14 .  thus  nitrogen  has  a  mass  number  of  14
