For the given S N 1 reaction in problem 8.1, overall reactants, overall products, and any intermediates are to be identified. Concept introduction: An S N 1 reaction is a unimolecular nucleophilic substitution reaction and is a two-step reaction. In the first step, the leaving group breaks off, taking its bond pair with the carbon atom, thus forming a carbocation. In the second step, the incoming nucleophile attacks the carbocation, forming the product. Stereochemistry is important and applicable for an S N 1 reaction. A species is an overall reactant or an overall product if it appears in the overall (net) reaction. A species is an intermediate if it is produced in the mechanism but does not appear in the overall reaction.

Interpretation Introduction

Interpretation:

For the given SN1 reaction in problem 8.1, overall reactants, overall products, and any intermediates are to be identified.

Concept introduction:

An SN1 reaction is a unimolecular nucleophilic substitution reaction and is a two-step reaction. In the first step, the leaving group breaks off, taking its bond pair with the carbon atom, thus forming a carbocation. In the second step, the incoming nucleophile attacks the carbocation, forming the product. Stereochemistry is important and applicable for an SN1 reaction.

A species is an overall reactant or an overall product if it appears in the overall (net) reaction. A species is an intermediate if it is produced in the mechanism but does not appear in the overall reaction.

3) Propagation of uncertainty. Every measurement has uncertainty. In this problem, we'll evaluate the uncertainty in every step of a titration of potassium hydrogen phthalate (a common acid used in titrations, abbreviated KHP, formula CsH5KO4) with NaOH of an unknown concentration. The calculation that ultimately needs to be carried out is: concentration NaOH 1000 x mass KHP × purity KHP molar mass KHP x volume NaOH Measurements: a) You use a balance to weigh 0.3992 g of KHP. The uncertainty is ±0.15 mg (0.00015 g). b) You use a buret to slowly add NaOH to the KHP until it reaches the endpoint. It takes 18.73 mL of NaOH. The uncertainty of the burst is 0.03 mL.. c) The manufacturer states the purity of KHP is 100%±0.05%. d) Even though we don't think much about them, molar masses have uncertainty as well. The uncertainty comes from the distribution of isotopes, rather than random measurement error. The uncertainty in the elements composing KHP are: a. Carbon: b. Hydrogen: ±0.0008…
