Question

non Gtrada 1) Add the correct number of bonded H's and electron pairs to make the bonding and formal charge correct. All the bonds between C, CI, O, and N are shown. Show the lone pair electrons and bonds to H on each molecule. You are given non-H atoms and correct formal charge. Group CI-C'-C-C-C C-O=C-C *N-C 2) Draw the structure and list what the atoms' electrons are doing in the molecule. (core electrons, valence electrons, orbitals, bonding, and lone pairs). i.e. H;CCFH each H has 1 electron, a valence electron, in the s orb H. it is in a covalent bond with C sp each C has 6 electrons, 2 e- in the first shell s orb, these are core e- 4 e- in the second shell, these are valence e-, in 4 orb - sp, sp', sp', p 3 valence e- in sp orb are sigma bonding with -H, -C, and -F, and 1 valence e- in the p orb is pi bonding with -C F has 9 e, 2 e- in the first shell s orb, core e 7e- in the second shell, valence e, in 4 orb - sp, sp' sp, sp 1 of these valence e- is covalently bonding to -C sp 6 of these valence e- are lone pairs in 3 sp' orb H. each H has BrCHCHNH2 Br has C has N has 3) Circle the conjugated atoms of the delocalized e system (connected p orbitals) for each molecule. Rank the following molecules from shortest to longest wavelength of absorption, Amax, in the Ultraviolet-Visible light spectrum. CH CH2 Rank des

Answer 1

0 Carbon atomic number is 6 and valence elections 4. oxygen atomic numberis & and valence elections 6 and it has two love pair elections 6 4 nonbonded clections sillogen atomic number is 7 and valence elections are 95 and has I love pair elections of e nonbonded clections chlorine atomic number is 17 and valence elections are 7 and has 3 love Paie elections. Folmal charge - Valence elections- (nonbonding electears - t number of bonds) 0 cl-e-c-c-c here carbon has fol mal charget! and number bonds are a substitute in the above formula carbon lone Paie elections are zelo +1=4-(0+2) To get formal charge from mal charge ti number a bonds must be 3. The extea bond is with hydrogen. So the lewis structure EC Similey remaining shown cu bolow @HH н н— —- I H-C 2- 0- I 1 ☺ Steucture of BOCHCH NH, is shown below Bro NH2 H NHA H.
