In the reactants there is a curvy arrow, what does the direction of the arrow indicate?
2 answers:
Answer: Option (C) is the correct answer.
Explanation:
When a curvy arrow is placed on the reactants then it shows that an electron is being transferred from one atom to another.
And, it is known that when donation or transfer of an electron occurs from one atom to another then it results in the formation of an ionic bond and the compound formed is known as ionic compound.
For example, sodium when chemically combines with chlorine atom then one valence electron is donated by sodium atom to the chlorine atom. This forms the ionic compound NaCl.
Thus, we can conclude that in the reactants there is a curvy arrow, the direction of the arrow indicate that the cations give away an electron and the anions accept electrons.

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.
