Nicotine present in tobacco has the following structure. Which nitrogen is more basic and explain your choice. CH3 2 ○ N1 is more basic as it is sp2 hybridized and more electronegative because of less S character. O N2 is more basic as it is sp3 hybridized and less electronegative because of less S character. ON1 is more basic as its lone pair has resonance.

For each molecule below, draw the conjugate acid or conjugate base or both if the molecule hasboth a conjugate acid and a conjugate base (e.g., water).

Which of the following compounds is the stronger base? Explain. or NH3 is a v base than NCI3. This is due to the difference in the electron withdrawing strength of Cl compared with H. v is more electronegative than and will v more electron density v the nitrogen than Thus, the nitrogen atom in NCI3 has a v positive charge than it does in NH3. The v positive charge means that is v difficult to add H* to NCI3 than it is to add H* to NH3. Is the compound Sb(OH)5 likely to be acidic, basic, or neutral in water? Justify your answer. Phosphorus and arsenic form acids of the form X(OH)n, so one would predict that antimony would be similar as it is in the same family. Based in the number of OH groups present, it should be However, antimony hydroxides are not stable and form oxides which are known to be amphoteric. Thus, Sb(OH)6 is in fact more likely to be

One of the three molecules is much more acidic than the other two. Identify the molecule and explain why it is so much more acidic that the other two. H H
