What characteristic frequencies in the infrared spectrum of your sodium borohydride reduction product will you look for to deter

mine whether the carbonyl group (in ethyl vanillin) has been converted to an alcohol functional group? That is, if the transformation has occurred, which characteristic frequencies should be present in the infrared spectrum, and which should be absent? How would the infrared spectrum for the sodium borohydride reduction product be affected if the product were still wet with water? Explain your reasoning.

Answer:

A)The characteristic frequency to look out for is  1720-1740 cm-1 (for C=O) for which will disappear in the end product but initially present in the reactant.

B)Characteristic frequency  present in the infrared spectrum will be at a peak of  3300-3400 cm-1 which will be due to O-H stretch.

C)If the product is wet with water there will be no change in the infrared spectrum

Explanation:

The characteristic frequency to look out for is  1720-1740 cm-1 (for C=O) for which will disappear in the end product but initially present in the reactant.

Characteristic frequency  present in the infrared spectrum will be at a peak of 3300-3400 cm-1 which will be due to O-H stretch.

If the product is wet with water there will be no change in the infrared spectrum

Answer:

The correct matching of the air mass and the letters in the word bank are given as follows;

1. Warm and humid                   ↔       D

2. Extremely cold and dry        ↔       B

3. Cold and dry                         ↔       A

4. Cold and humid                    ↔       C

5. Warm and dry                       ↔        E

Where;

A Represents continental polar

B Represents Artic

C Represents Maritime Polar

D Represents Maritime Tropical

E Represents Continental Tropical

Explanation:

A. A continental polar is one that can be described as a cold and dry climate as the region is located at a further away from the oceanic water bodies that add humidity to the climate

B. The regions of the Artic and the Antarctic have very limited amount of precipitation every year because the air is very cold as well as dry

C. A polar climate is a cold climate region, while a maritime climate is humid.

Therefore, the maritime polar climate combines both cold and humid conditions

D. A warm and humid region has high rainfall and humidity, as such the maritime climate which are humid and the tropical climate, which are warm, combine to give a warm and humid climate

E. The continental tropical climate can be described as warm and dry, compared to the continental water bodies, due to the location being distant from and therefore, the absence of high moisture containing wind that comes from the oceans.
