Answer 1

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

(a)

Interpretation:

The structure of 6-methyloctanal should be drawn.

Concept Introduction:

In aldehyde nomenclature, aldehydes are identified by the suffix "-al". C-1 is given to the aldehyde carbon in numbering the parent chain, but this number is omitted in the name.

Interpretation Introduction

(b)

Interpretation:

The chirality center of 6-methyloctanal should be labeled.

Concept Introduction:

Chirality is a phenomenon referred to when a molecule's mirror image is non-superimposable. That means a molecule and its mirror image are not similar. In organic molecules, chiral center is defined as the carbon with four different groups.

Interpretation Introduction

(c)

Interpretation:

Products formed when 6-methyloctanal is treated with H₂ and a palladium catalyst should be determined.

Concept Introduction:

In a reduction of an organic molecule, either the number of C-O bonds decreases or number of C-H bonds increases. So when an aldehyde is reduced by H₂ in the presence of Pd catalyst, C=O double bond is reduced to C-O single bond and H₂ is added across this C=O double bond forming a primary alcohol.

6. A solution (0.0004 M) of Fe(S2CNEt2)3 (see the structural drawing below) in chloroform has absorption bands at: 350 nm (absorbance A = 2.34); 514 nm(absorbance A = 0.0532); Calculate the molar absorptivity values for these bands. Comment on their possible nature (charge transfer transitions or d-d S N- transitions?). (4 points)

What is the mechanism for this?

For questions 1-4, consider the following complexes: [Co(CN)6], [COC14]², [Cr(H2O)6]²+ 4. Room temperature (20°C) measurement of molar magnetic susceptibility (Xm) for Fe(NH4)2(SO4)2×6H2O is 1.1888 x 102 cgs (Gaussian units). Calculate effective magnetic moment and provide a number of unpaired electrons for the iron ion. Use this number to rationalize the coordination geometry around iron center. (4 points)
