0,0, -2 2) Assign formal charges to each atom in the following structures. Show your work in the space below. : co: :: H:C:C:H HicỀN: H:CO:H C= C = H= C= 0 = H 0.= N= 0.- H=

Answer 1

Am. 2 formal = (mo. of Valence charge no. of e-bonded an covalent bond no of elections 2 - (00:4 electrons wis lone pair) り . ċ:: o: ca a 4 2 - 2 C a 4-3-2 - 1 C = -1 0 = 6 - G ܝ2 0 = + 1 a Il G-3-2 +1

(نة : H:c::: - ا = C - امى از O C ن = C لل 2 - 1 - ا ۲ - 0 3 لم ( نانه ui : ۸::c : ا H - 1 - 2 - 0 | - = 0 - ا - C = 0 C = 6 0 - اN مربع (يع N) - 5 - 5 - 6 2 || - 0 ) : :: H; : : : : Os= ( - 2 - ا - C 0 = 0 | مي 6 ۔ - - - 4 0a = 6 - 6 _ + 1 H = 2 2 - D فهم

ans. z. :02 Hi Ć::o,:4 c =4-8_0=0 2 0, O, = 6- 6 2 =+1 2 O = 6-26 H= a =0 ele = -1 Structure = :7 + H-C =0 -H The above structure is precited because in this one o is tvely charged and one is-vely charged and all other atoms have oformal charge this the requirements. satisfying

B :0 Hi Ci 0,11 C = 4 - 8 11 0 8100 0, 6 - 4 = 0 4 a eo 6 - 4 - 4 = 0 2 и-- 1 - 2 2 co have o Since all the atoms formal charge thus the structure with o formal charge is :0 " HE Fö-H H
