3. What are the formal charges on each of the atoms in the following structure? H;C-CEN-ö: 4. What is the molecular formula for the following compound? OH 5 Indicate which answer best describes the two molecules Br and Br a) Resonance structures b) Identical structures c) Constitutional isomers d) Different compounds with different constitutions 6 What would be the line-bond structure for (CH3)3CCH2CH(CH3)2?

Answer 1

co) what are } atoms the formal charges on each of the in the following structure CHE = CE.N-O com Қ H N- io; H carbon joined he named for are convenience hydrogen c* to and carbon with nitrogen as as e ** Then, H 1 ** C CEN H * ;ö: H formal charge total number of valance electron I total neimber total number bonding electroni non 2 of Bonding electron

5 Now, number of valance electron of c 4 number of valance electron of N number of valance electron of of formal charge => 1 6 number valance electron of h 0-$12) all Hydrogens are same then formal charge all hydrogen is formal charge c* -.0.-18). formal charge en C 0 - ļ18) o M formal charge on nitrogenin' 1 → 5-0 - 118) formal charges = 6 6.- 6-12) o' charges on oxygen 1

80, -1 ti ( и CEN QJ hehat is the molecular formula for the following compound es OH.

801n Hobular or chemical formata is count of each element present in a molecule H - Lahy - H H and carbon is į total number of rydrogen is a so its chemical formula is CH4 eg 0:- C=0 mobecular formula formula is . Now in this question OH

we can say CHE = СНs CH O-HT ro 9 8 1.) total number 왕 carbon atom total number of reydrogen atomi total number atom : of oxygen so , the molecular formula is Cg H04 5 ) Indicate which answer best describe the two molecules and Br x Br

801 There is not given wh, it is notated or not. Resonance structures :-No. They There is are not resonance structures conjugation: as, b ) identical structures 2 Вл 3 t IUPAC name IUPAC is Name is 2-bromo- 2.4 - dimethyl pentane 2- bromo-2-4 limethyl pentane . both are identical. obtained due conformation isomer. no. of forms which are single covalent about a Infinite notation free bond co.bond , to

SA They not conformation isomers there .is no, rotation constitutione isomer or structure isomer → e compound having same molecular formal formula , same molecular mass beut diffrent structure called structural isomers both not diffrent compounds. They are identical ta are What Whould would be the line band structure for ( Ma), C CHE.CHECHg),? san bond line structure - This is in which a basicaly representation single bond is represent by ä line double bond is 2 lines eg. CH CHA CH CHE 1 2 4 2 bond liné structure

eg. Сн, соо ч ion line to bond structure OH Now, for this question CH3 H Inc 대 को CH2 CH 3 3 2 5 3 al CH 3 CH bond line structure is
