- Problem Draw Lewis structures for the following:(a) Ethylene (C2H4), the most important reactant in the manufacture of polymers(b) Nitrogen (N2), the most abundant atmospheric gasPlan We show the structure resulting from steps 1 to 4: placing the atoms, counting the total valence electrons, making single bonds, and distributing the remaining valence electrons in pairs to attain octets. Then we continue with step 5, if needed.arrow_forwardI dont understand. Select the bonds in the 3D representation of thymine below that are multiple bonds. (Hint: Consider the number of bonds attached to an atom in the image compared to the normal valence of that atom. In a valid structure, the number of bonds to an atom will equal the valence of that atom.)arrow_forwardProblem What amount (mol) of each ion is in each solution?(a) 5.0 mol of ammonium sulfate dissolved in water(b) 78.5 g of cesium bromide dissolved in water(c) 7.42×1022 formula units of copper(II) nitrate dissolved in water(d) 35 mL of 0.84 M zinc chloridePlan We write an equation that shows 1 mol of compound dissociating into ions. (a) We multiply the number of moles of ions by 5.0. (b) We first convert grams to moles. (c) We first convert formula units to moles. (d) We first convert molarity and volume to moles.arrow_forward
- Below are two sets of resonance structures. Where applicable provide the missing curved arrow notation, lone pair electrons, and nonzero formal charge. Do not delete or add any bonds or atoms.arrow_forwardWhat is the relationship between the following two molecules? Problem viewing the image. Click Here O They are the same compound. O They are structural isomers. O They are stereoisomers. O They are completely different compound and not isomers O They are isotopes.arrow_forwardIn the molecule shown label the indicated bonds with either their hybridization (sp,sp2,sp3) or the type of bond present (sigma, pi )arrow_forward
- Draw each of the species in Problem as a condensed formula.arrow_forwardProblem Draw a Lewis structure and identify the octet-rule exception for (a) H3PO4 (draw two resonance forms and select the more important); (b) BFCl2.Plan We draw each Lewis structure and examine it for exceptions to the octet rule.(a) The central atom is in Period 3, so it can have more than an octet.(b) The central atom is B, which can have fewer than an octet of electrons.arrow_forwardSolve correctly please, with some explanation need.arrow_forward
- I am wondering why there is a need for resoance structures if the molecule already has a neutral charge. Wouldn't these all be insignificant resonance structures (as there is unnecessary charge separation)? Perhaps they are only depicting these structures for the purpose of showing high/low electron density (which was what the question was asking for)? 1 picture shows answer, another shows problem (it is (b)).arrow_forwardProblem attachedarrow_forwardDraw the resonance structure that results from the following electron flow arrows. Note: Include formal charges and lone pairs where applicable.arrow_forward
