The hemiacetal and acetal in the mechanism in Equation 18-13 are to be identified. Also the steps that make up an S N 1 reaction are to be circled. Concept introduction: If an aldehyde or ketone is treated with a large excess of an alcohol under acidic conditions, then the hemiacetal produced from nucleophilic addition reacts further to form an acetal, in which two alkoxy (RO) groups are bonded to the same carbon. A hemiacetal group is an R 2 C ( OH ) ( OR ) or RCH ( OH ) ( OR ) . An acetal group is R 2 C ( OR ) 2 or RCH ( OR ) 2 .

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

Interpretation Introduction

Interpretation:

The hemiacetal and acetal in the mechanism in Equation 18-13 are to be identified. Also the steps that make up an SN1 reaction are to be circled.

Concept introduction:

If an aldehyde or ketone is treated with a large excess of an alcohol under acidic conditions, then the hemiacetal produced from nucleophilic addition reacts further to form an acetal, in which two alkoxy (RO) groups are bonded to the same carbon. A hemiacetal group is an R2C(OH)(OR) or RCH(OH)(OR). An acetal group is R2C(OR)2 or RCH(OR)2.

Carbohydrates- Draw out the Hawthorne structure for a sugar from the list given in class. Make sure to write out all atoms except for carbons within the ring. Make sure that groups off the carbons in the ring are in the correct orientation above or below the plane. Make sure that bonds are in the correct orientation. Include the full name of the sugar. You can draw out your curve within the text box or upload a drawing below.

How many milliliters of 97.5(±0.5) wt% H2SO4 with a density of 1.84(±0.01) g/mL will you need to prepare 2.000 L of 0.110 M H2SO4? If the uncertainty in delivering H2SO4 is ±0.01 mL, calculate the absolute uncertainty in the molarity (0.110 M). Assume there is negligible uncertainty in the formula mass of H2SO4 and in the final volume (2.000 L) and assume random error.
