【】How to transform Ethene come Ethanoic mountain or Acetic Acid||How Ethanoic acid Is all set from Ethene


How to convert Ethene to Ethanoic acid or Acetic acid Answer: To transform ethene to ethanoic acid,we will adopt four steps:              Step-1: Ethene reacts v HBr and we obtain 1-bromo ethane.            Step-2: 1-bromo ethane reacts with aqueous KOH and we gain ethanol.            Step-3: Ethanol is oxidized through K₂Cr₂O₇ add to H₂SO₄ and also we get ethanal.            Step-4: Again,ethanal is oxidized by K₂Cr₂O₇ to add H₂SO₄ and also we gain ethanoic acid or acetic acid. Now see every the actions at a glance.

SO2 Lewis Structure   Answer: below is the definition of SO2 Lewis structure. SO2 Lewis framework (sulfur dioxide electron period structure) is that kind of diagram where we display the total 18 valence electrons of SO2 together dots , or dots and dashes(-).In Lewis structure,it is typical that a bonding pair of 2 electrons can be shown by  dash(-) or dots(●●) however a lone pair of two electrons is shown by dots<●●>. In SO2 Lewis structure,there room two double bonds that space going from the atom sulphur come oxygens. In SO2 Lewis framework ,there are completely five lone pairs of electrons.The each  oxygen has two lone bag 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 however the sulfur atom don't monitor the octet rule.It has an ext than eight electrons.
