First, draw your chosen compounds including any non-bonding electrons and non-zero formal charges Circle and name any pH-sensitive functional groups. Choose an organic solvent that will dissolve both or your compounds and an aqueous solution (i.e. conc. aqueous NaOH, 5% aq. NaHCO3, or 3M HCl) that would successfully separate the two compounds selected.

Alkyne can play as acid in presence of strong base. After deprotonation, what is the hybridization of the carbon who forms anion?

Need help with 1-4 please. Will submit another time as well. Pre-laboratory questions

Hydroxide acts as a nucleophile in protein degradation by hydrolysis of the peptide bond in water. Draw out an arrow pushing mechanism of the hydrolysis of a peptide bond. Identify the nucleophile and the electrophile in this reaction.

Complete the electron‑pushing mechanism for the base‑promoted hydrolysis of an ester shown in the panels. Add atoms, bonds, nonbonding electron pairs (lone pairs), charges, and curved arrows.

Can you help me with part A and part B, please?

In a reaction where a carboxylic ester reacts with water to produce an alcohol and a carboxylate (or carboxylate salt) as the products, the reaction is called ___ , and requires ___ to occur. esterification; strong base saponification; strong base saponification; strong acid acid-catalyzed ester hydrolysis; strong acid esterification; strong acid

Oa) An amine can be formed when 2-iodopentane is heated with ammonia in a sealed tube. This is an example of a nucleophilic substitution reaction. i) Provide a full equation (using condensed formula) for this reaction. You should name the reactants and the overall products as part of your response. ii) Name the organic product formed from this reaction and draw it's displayed structure. iii) Provide a 'curly arrow' mechanism (in displayed formula) with an accompanying explanation for this process. iv) Describe a characteristic test (with the result that would be observed) to show the presence of the amine produced upon completion of the nucleophilic substitution reaction. b) The amine produced in the above reaction forms a mixture of two optical isomers. i) Draw the 3D structures of the two isomers of the amine product that you named and produced a drawing of in part a ii). ii) With reference to a different named example, explain the term 'optical isomer'. You should draw the 3D…
