【】How to convert Ethene come Ethanoic mountain or Acetic Acid||How Ethanoic mountain Is prepared from Ethene
How to convert Ethene come Ethanoic acid or Acetic acid Answer: To transform ethene come ethanoic acid,we will take on four steps: Step-1: Ethene reacts through HBr and also we gain 1-bromo ethane. Step-2: 1-bromo ethane reacts with aqueous KOH and also we get ethanol. Step-3: Ethanol is oxidized by K₂Cr₂O₇ plus H₂SO₄ and also we acquire ethanal. Step-4: Again,ethanal is oxidized by K₂Cr₂O₇ add to H₂SO₄ and also we gain ethanoic acid or acetic acid. Currently see all the actions at a glance.

SO2 Lewis Structure Answer: here is the definition of SO2 Lewis structure. SO2 Lewis framework (sulfur dioxide electron dot structure) is that form of diagram where we present the complete 18 valence electrons of SO2 as dots , or dots and also dashes(-).In Lewis structure,it is typical that a bonding pair of 2 electrons have the right to be presented by dash(-) or dots(●●) but a lone pair of 2 electrons is displayed by dots<●●>. In SO2 Lewis structure,there space two double bonds that space going indigenous the atom sulphur come oxygens. In SO2 Lewis framework ,there are entirely five lone bag of electrons.The each oxygen has actually two lone pairs of electrons and also the sulphur atom has actually one lone pair of electrons. In SO2 Lewis structure ,the oxygen atoms follow the octet rule yet the sulfur atom don't monitor the octet rule.It has much more than eight electrons.
