- Write Lewis structures for the Cis -trans isomers of CH3CH = CHCl.arrow_forwarda. How many sticks did you need to make the skeleton structure?____________ b. How many sticks are left over? ____________ If your model is to obey the octet rule, each ball must have four sticks in it except for hydrogen atom balls, which need and can only have one. Each atom in an octet rule species is surrounded by four pairs of electrons. c. How many holes remain to be filled? ____________ Fill them with the remaining sticks, which represent nonbonding electron pairs. Draw the complete Lewis structure for NH2Cl using lines for bonds and pairs of dots for nonbonding electrons.arrow_forwardFormamide, HC(O)NH2, is prepared at high pressures from carbon monoxide and ammonia, and serves as an industrial solvent (the parentheses around the O indicate that it is bonded only to the carbon atom and that the carbon atom is also bonded to the H and the N atoms). Two resonance forms (one with formal charges) can be written for formamide. Write both resonance structures, and predict the bond angles about the carbon and nitrogen atoms for each resonance form. Are they the same? Describe how the experimental determination of the HNH bond angle could be used to indicate which resonance form is more important.arrow_forward
- Answer the questions based on the resonance structures of S2O32– (thiosulfate) below. See attatched photo for more information. Draw an “X” through the resonance structure that is not chemically possible. On the remaining three resonance structures, write in any non-zero formal charges. Of the remaining three structures, circle the structure that will contribute the least to the resonance hybrid. Draw a resonance hybrid (including partial “δ” and full charges) for S2O32–.arrow_forwardDraw the Lewis-dot structure for C4 H10 below.

- While carbon mostly forms 4 bonds (and has a full octet), this is not always true. During reactions, carbon intermediates often only make three bonds and do not follow this rule. a. Which of these three carbon atoms (to the right) has an incomplete octet? b. How many more electrons would be needed to fill each octet? c. What are the formal charges on these carbon atoms?arrow_forward2) Build C6H6 as a ring. What do you notice about the placement of the bonds? This is an example of resonance.

(a) All contributing structures must have the same number of valence electrons. (b) All contributing structures must have the same arrangement of atoms. (c) All atoms in a contributing structure must have complete valence shells. (d) All bond angles in sets of contributing structures must be the same.arrow_forwardDraw the Lewis structure of BH4- and use your Lewis structure to help fill in the missing numbers.
