- Select all molecules that are expected to be polar.Which whould you expect to be more polar a C-O or a C-F bond?. Explain pleaseProblem 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.
- Problem Which of the following substances exhibits H bonding? For any that do, show the H bonds between two of its molecules. (a) C̟H, (b) CH;OH (c) CH3C–NH,Select ALL of the following that can be used to explain the polarities of NO2 and SeCl42- (these molecules are mentioned in earlier questions). NO2 has a permanent dipole moment or a net dipole moment greater than zero whereas SeCl42- has no net or zero dipole moment. Both molecules are symmetrical and hence nonpolar Due to their respective shapes, in NO2 the bond dipole moments reinforce each other whereas in SeCl42- they cancel out each other. NO2 has no net dipole moment and SeCl42- has a net dipole moment greater than zero. NO2 is an unsymmetrical molecule whereas SeCl42- is a symmetrical ion.Determine the polarity of the following molecules. If polar, indicate the partially negative end. CH4 BF3 H2S Kindly explain.
- Answer the following question about acetonitrile (CH3C≡N:). Question: In what type of orbital does the lone pair on N reside?Answer the following question about esmolol (attached) , a drug used to treat high blood pressure sold under the trade name Brevibloc. Question: Label all sp2 hybridized C atomsAccording to the VSEPR model, the arrangmenet of electron pairs around NH3 and CH4 is? 1) different because in each case there are a differnent number of atoms around the centrral atom. 2) different or the same, becasue depending on the condition leading to maximum repulsion 3) the same, becuase in each case there are the same number of electron groups around the central atom 4) different, because in each case there are different numbers of electron groups around the central atom 5) the same, becuase both nitrogen and carbon are both in the second period
