      Step-3:

Methanol reacts with phosphorus triiodide(PI₃ )and produce iodomethane(CH₃-I).

   Step-4:

Iodomethane(CH₃-I) reacts with KCN (alcoholic) and produce ethanenitrile(CH₃-CN).
Iodomethane(CH₃-I) reacts with KCN (alcoholic) and produce ethanenitrile(CH₃-CN)






Step-5:Ethanenitrile(CH₃-CN) is reduced by sodium(Na) and ethanol(CH₃-CH₂-OH) and we get ethanamine or ethyl amine(CH₃-CH₂-NH₂).





Step-6:Ethanamine or ethyl amine(CH₃-CH₂-NH₂) reacts with NOCl and produce chloroethane(CH₃-CH₂-Cl).



Step-7:Chloroethane(CH₃-CH₂-Cl) reacts with Zn-Cu +CH3OH and produce ethane(CH₃-CH₃).

Step-1:Ethane(CH₃-CH₃) reacts with chlorine in presence of sunlight and produce chloroethane(CH₃-CH₂-Cl).




Step-2:Chloroethane(CH₃-CH₂-Cl) reacts with aqueous KOH and produce ethanol(CH₃-CH₂-OH).




Step-3:Ethanol(CH₃-CH₂-OH) is oxidized by potassium dichromate (K₂Cr₂O₇) and sulphuric acid and we get ehanal(CH₃-CHO).


Step-4:Ehanal(CH₃-CHO) is also oxidized by potassium dichromate (K₂Cr₂O₇) and Sulphuric acid (H₂SO₄) and we get ethanoic acid(CH₃-COOH).



Step-5:Ethanoic acid(CH₃-COOH) is heated with sodalime (NaOH+CaO).Thus one molecule CO₂ goes out and we get methane(CH₄).

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.

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.
