The correct common name for the given compound has to be chosen from the given options. Concept Introduction: Common name: Common name for alcohol can be obtained by considering the hydroxyl group to be substituted on an alkyl group. The common name for alcohol can be given as alkyl alcohol. IUPAC rules for naming alcohols that contain single hydroxyl group: Longest carbon chain has to be identified that contains hydroxyl group also. The chain name is obtained by replacing the letter “-e” in alkane with “-ol”. The numbering has to be given so that the hydroxyl group gets the least numbering. Name and location of any other substituent present in the chain has to be identified. If in a ring the hydroxyl group is present, then that carbon is numbered 1 and the numbering then proceeds counterclockwise or clockwise in a way that substituents present if any gets the least numbering. Hydroxyl group as a substituent in a molecule is named as hydroxy group rather than hydroxyl group. IUPAC rules for naming alcohols that contain more than one hydroxyl group: The same rules said above is followed but the prefix di-, tri-, tetra etc is added corresponding to the number of hydroxyl groups that is present.

Interpretation Introduction

Interpretation:

The correct common name for the given compound has to be chosen from the given options.

Concept Introduction:

Common name:

Common name for alcohol can be obtained by considering the hydroxyl group to be substituted on an alkyl group. The common name for alcohol can be given as alkyl alcohol.

IUPAC rules for naming alcohols that contain single hydroxyl group:

Longest carbon chain has to be identified that contains hydroxyl group also. The chain name is obtained by replacing the letter “-e” in alkane with “-ol”.

The numbering has to be given so that the hydroxyl group gets the least numbering.

Name and location of any other substituent present in the chain has to be identified.

If in a ring the hydroxyl group is present, then that carbon is numbered 1 and the numbering then proceeds counterclockwise or clockwise in a way that substituents present if any gets the least numbering.

Hydroxyl group as a substituent in a molecule is named as hydroxy group rather than hydroxyl group.

IUPAC rules for naming alcohols that contain more than one hydroxyl group:

The same rules said above is followed but the prefix di-, tri-, tetra etc is added corresponding to the number of hydroxyl groups that is present.

(a 4 shows scanning electron microscope (SEM) images of extruded actions of packing bed for two capillary columns of different diameters, al 750 (bottom image) and b) 30-μm-i.d. Both columns are packed with the same stationary phase, spherical particles with 1-um diameter. A) When the columns were prepared, the figure shows that the column with the larger diameter has more packing irregularities. Explain this observation. B) Predict what affect this should have on band broadening and discuss your prediction using the van Deemter terms. C) Does this figure support your explanations in application question 33? Explain why or why not and make any changes in your answers in light of this figure. Figure 4 SEM images of sections of packed columns for a) 750 and b) 30-um-i.d. capillary columns.³

fcrip = ↓ bandwidth Il temp 32. What impact (increase, decrease, or no change) does each of the following conditions have on the individual components of the van Deemter equation and consequently, band broadening? Increase temperature Longer column Using a gas mobile phase instead of liquid Smaller particle stationary phase Multiple Paths Diffusion Mass Transfer
