a)

Interpretation Introduction

Interpretation:

From the Table 24-2, the elution order of Hexane, Heptane, Octane, Benzene, Butanol and 2-pentanone has to predicted from the column containing Poly(dimethylsiloxane).

Concept Introduction:

Kovats retention index:

Retention index, I for linear alkane equals 100 times the number of Carbon atoms.

For a molecule of Octane, I=800

For a molecule of Nonane, I=900

The elution of compound between Octane and Nonane will have retention index between 800 and 900 is calculated using the formula,

I=100[n+(N-n)logtr'(unknown)-logtr'(n)logtr'(N)-logtr'(n)]

Where, n = number of Carbon atoms in smaller alkane

N = number of Carbon atoms in larger alkane

tr'(n) = adjusted retention time of smaller alkane

tr'(N) = adjusted retention time of larger alkane

To predict the elution order of Hexane, Heptane, Octane, Benzene, Butanol and 2-pentanone from the column containing Poly(dimethylsiloxane)

Interpretation Introduction

Interpretation:

From the Table 24-2, the elution order of Hexane, Heptane, Octane, Benzene, Butanol and 2-pentanone has to predicted from the column containing (diphenyl)0.35,(dimethyl)0.65polysiloxane .

Interpretation Introduction

Interpretation:

From the Table 24-2, the elution order of Hexane, Heptane, Octane, Benzene, Butanol and 2-pentanone has to predicted from the column containing poly(ethylene glycol).

Concept Introduction:

Predict the major products of the following organic reaction: O O + A ? Some important notes: • Draw the major product, or products, of the reaction in the drawing area below. • If there aren't any products, because no reaction will take place, check the box below the drawing area instead. • Be sure to use wedge and dash bonds when necessary, for example to distinguish between major products that are enantiomers.
