Question

Lewis Structure Problem Set You must draw the Lewis structure with formal charges) for each molecullion to receive full credit 1. How many of the following have lone pairs on the centralatom? PFS NCI Seo 2. In how many of the following does the central atom contain exactly 1 double bond? NHN NO: NH: H-N -H 0. b= -5: HNH 3. How many of the following have at least one atom with a formal charge that is not zero? Which atom(s) have the non-zero charge? Remember you have to draw all of the Lewis structures with formal charges for all atoms/ions on this entire problem set (not just this question). 10- OH SO 4. How many single, double, and triple bonds are present in the best Lewis structure of NCON. Note that there are two central atoms in this compound and the atoms are bonded in the presented order: N-C-C-N NEC-CEN 2 I triple bonds single bond

Answer 1

Ang:-1:- • Pfy → Hybridisation: 8p24 - Trigouel lyramidal geeney - with five bond pairs and zero love puiss. three band pcuss and one lone pair Se og sp ² Bent geometry with two band pains and one love pais. cely sp3 four bond tetrahedaal geometry having sous paiss and neoo lone pains. Hence only nel and seo, have lone puiss on the central atom. Q.2: NH₂ pyzamial geometsy (2 no double band, throee single bond) NO3 → sp² Trigenal . planer three single band r : one double band 10 Nity + sp² tedsa hedaal I fores single band HTH no double bond Only 10g contains exactly a deuble band. a formula of formal charge valence - Nonbonding . Bonding electsons elections valance electrons -

5044 . Q: 7a- 504 OH +0=s=o formal charge of s = 6-1 0 →6-6-4--| H → 1-0 - 42-0 & Hence none of the comprends have at least one atom with nonteso formal charge. * 'o'atom has the nonzero 0 6 = -4-cy = 6 6- 6-2=-1 0 102 - 0 =1 charge (-1) I: 7-4-6, -0 O* = 6 -4 -42-0 O = 6-6-24, = -1 Q-4 single bond trèple bond :NEC EGEN There are some one single bonda boobs two toiple bonds md zero dorchle bonde in NCEN.
