Question

first one wasnt visible

which the w ood trucures! O= C- 0 H-A- o=C-

Answer 1

Let us see number of elections in valency shell for different atoms. Atomic Electronic configuration atom Aps 17 15asapo 35'3p Il Troll 3p5 o -8 15as'ap* wy] avl1/1 s - 16 15 as ap" I 333 D AS - 18 15 25 ap huay 1 38 3p Lewis structures bp these atom H ... : .C

Numbers of bonds depends en Valence elecons Carbon forms four bonds. The compounds in which carbon foms more than four bonds are wrong H. H- C YC H Carbon bas 6 bonds. So this structure is wrong. 5 bonds y go wrong Stoucture slone paid + one bond y correct Hm. AF: Angon should have 4 lone pairs of electrons. Bhere two elections of one lone pair are sipale bonds with HCF atoms and remains with 3 lone pair op.eledaos. In this all the three atoms have Correct number op ele choonx. So Coronet

ö=ci - 0 Two bonds It gained one Lechon electron so R addition to + Twolone pairs of electronx Should have 31 one pairs & single bond but one lone pair isured two lone pair op elections tone extra tone pair is Potrert for two bonds. So remains with two lone pairs and 3bonds. -ve change indicates gain of one ele cloon. is also correct. So this stoucture i finally, structures A&B are wrong. & D are correct Lewis dot structures .. option 3 is correct.
