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.

rank the following in increasing acidity

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

Predict the stronger acid in each pair HBrO3 or HBrO2

Use following: a) Atoms b) Resonance c) Induction d) Orbitals

Physostigmine is used in the treatment of glaucoma. Within this structure, the atom indicated by least basic. 2 CH3 H₂C souf 1 NHCH3 4 2 (most basic), 4 (least basic) 1 (most basic), 4 (least basic) 2 (most basic), 3 (least basic) 1 (most basic), 3 (least basic) None of the above is most basic, while atom is

Which carbon has the most acidic proton in the molecule below? B D 4 B D C CH₂

Predict the position of the equilibrium for the reaction and provide a brief explanation. (The acidic protons are shown in red.) A B Forward direction is favored because oxygen is more electronegative, making B the weaker base and D the stronger acid. O Reverse direction is favored because oxygen is more electronegative, making B the weaker base and D the stronger acid. O Forward direction is favored because sulfur is larger, making C the weaker base and A the stronger acid. Reverse direction is favored because sulfur is larger, making C the weaker base and A the stronger acid.

Which compound would be the strongest acid? O CH3CCI2CH2CO2H O CH3CHCICHCICO2H O CH3CH2CCI2CO2H O CICH2CHCICH2CO2H
