【10 Steps】How Can We Convert Propene to Ethene?

How to Convert Propene to Ethene




              Step-1:

Propene reacts with HBr in presence of Hydrogen peroxide(H₂O₂) and we get 1-bromo propane(CH₃-CH₂-CH₂-Br).


           
          Step-2:

1-bromo propane (CH₃-CH₂-CH₂-Br) reacts with aqueous KOH and we get propanol(CH₃-CH₂-CH₂-OH).
1-bromo propane (CH₃-CH₂-CH₂-Br) reacts with aqueous KOH and we get propanol(CH₃-CH₂-CH₂-OH).



       
           Step-3:

Propanol(CH₃-CH₂-CH₂-OH) reacts with K₂Cr₂O₇ in presence of H₂SO₄ and we get propanal(CH₃-CH₃CHO).


Step-4:

Propanal(CH₃-CH₃CHO) again reacts with K₂Cr₂O₇ in presence of H₂SO₄ and we get propanoic acid(CH₃CH₂COOH).


Step-5:

Propanoic acid(CH₃CH₂COOH) reacts with Conc.NH₃ and we get ammonium propanoate(CH₃CH₂COONH₄).


Step-6:

Ammonium propanoate(CH₃CH₂COONH₄) is heated and we get propanamide (CH₃-CH₂CONH₂).




Step-7:

Propanamide[CH₃-CH₂CONH₂) reacts withBr₂ in presnce of KOH and we get ethyl amine(CH₃-CH₂NH₂).


Step-8:

Ethyl amine(CH₃-CH₂NH₂) reacts with NaNO₂+HCl and we get ethanol(CH₃CH₂OH).

Step-9:

Ethanol(CH₃CH₂OH) reacts with PCl₅ and we get chloro ethane(CH₃-CH₂Cl).

Step-10:
Chloro ethane(CH₃-CH₂Cl) alcoholic KOH and we get ethene(CH₂=CH₂).

Selenium has six valence electrons. Read:CO2 Lewis Structure Explanation: Now I am going to show you how to find valence electrons in selenium  in just 5 steps. Add caption              Step-1: First, find the atomic number of  selenium  from periodic table. From periodic table ,we see that the atomic number of  selenium  is 34.                  Step-2: We know that the atomic number of  selenium  is 34.So  selenium  has 34 protons and 34 electrons as the charge of electrons and protons are equal but opposite in nature.The charge of proton is +1 and the charge of electron is -1.

Answer: To convert ethene to ethanoic acid,we will adopt four steps:              Step-1: Ethene reacts with HBr and we get 1-bromo ethane.            Step-2: 1-bromo ethane reacts with aqueous KOH and we get ethanol.            Step-3: Ethanol is oxidized by K₂Cr₂O₇ plus H₂SO₄ and we get ethanal.            Step-4: Again,ethanal is oxidized by K₂Cr₂O₇ plus H₂SO₄ and we get ethanoic acid or acetic acid. Now see all the steps at a glance.

【 】SO2 Lewis Structure ,Valence Electrons ,Formal Charge,Polar or Nonpolar

SO2 Lewis Structure   Answer: Here is the definition of SO2 Lewis structure. SO2 Lewis structure (sulfur dioxide electron dot structure) is that type of diagram where we show the total 18 valence electrons of SO2 as dots , or dots and dashes(-).In Lewis structure,it is common that a bonding pair of two electrons can be shown by  dash(-) or dots(●●) but a lone pair of two electrons is shown by dots[●●]. In SO2 Lewis structure,there are two double bonds that are going from the atom sulphur to oxygens. In SO2 Lewis structure ,there are totally five lone pairs of electrons.The each  oxygen has two lone pairs of electrons and the sulphur atom has one lone pair of electrons. In SO2 Lewis structure ,the oxygen atoms follow the octet rule but the sulfur atom don't follow the octet rule.It has more than eight electrons. In SO2 Lewis structure,we get nine pairs of electrons.Out of nine pairs of electrons,SO2 has four bond pairs of electrons and five lone pairs of electrons.Here,each oxy

H₂SO₄ + NaOH ----->Na₂SO₄ +H₂O Step-2:In the left side, we have  H SO₄  Na O To balance this reaction means we need to equalize the number of these above atoms and polyatomic ion. Step-3:Now balance Na atom first.In the left hand side,we have one Na but in the right side,we have two Na.So to balance Na ,we need to put 2 before NaOH in the left side.

  How many valence electrons does C6H12O6 (glucose) have ? Answer : In  C₆H₁₂O₆ ,we get 6 carbon atoms , 12 hydrogen atoms and 6 oxygen atoms. Firstly, carbon is an element of group 4A,so it has 4 valence electrons. Secondly,Hydrogen is an element of group 1A.So it has one valence electrons. Thirdly, oxygen is an element of group 6A .So it has six valence electrons. For   C₆H₁₂O₆ , 6 C = 6 × 4 = 24 12 H =12 × 1 =12 6 O = 6 ×6    = 36 Totally, we are getting 24 + 12 + 36 = 72 valence electrons in glucose (C6H12O6). Next
