Concept explainers
(a)
Interpretation:
The given compound has to be named and it is reducing sugar or not is to be predicted.
Concept Introduction:
The naming of the reducing and nonreducing sugars is done on the basis of position of hydroxyl group present at each carbon atom in the sugar which is classified on the basis of alpha, beta, D and L sugars. The sugar which has free
The name of the sugar is determined on the basis of position of hydroxyl group which is given as,
- The sugar containing hydroxyl group on the carbon atom connected to methanol group on the right side is name as D sugar.
- The sugar containing hydroxyl group on the carbon atom connected to methanol group on the left side is name as L sugar.
- The sugar containing hydroxyl group on the carbon atom connected to oxygen atom at equatorial position is said to be alpha sugar.
- The sugar containing hydroxyl group on the carbon atom connected to oxygen atom at axial position is said to be beta sugar.
- The name of alkyl group attached to the hydroxyl groups written before the name of sugar.
Reducing sugar is the sugar which is capable to act as a reducing agent. The sugar which contains aldehyde and ketone groups in free state acts as reducing sugar and the sugar which does not contain aldehyde and ketone group in free state are known as nonreducing sugars.

- Digitalis is a preparation made from the dried seeds and leaves of the purple foxglove, Digitalis purpurea, a plant native to southern and central Europe and cultivated in the United States. The preparation is a mixture of several active components, including digitalin. Digitalis is used in medicine to increase the force of myocardial contraction and as a conduction depressant to decrease heart rate (the heart pumps more forcefully but less often).arrow_forwardEthyl butyrate, CH3CH2CH2CO2CH2CH3CH3CH2CH2CO2CH2CH3, is an artificial fruit flavor commonly used in the food industry for such flavors as orange and pineapple. Its fragrance and taste are often associated with fresh orange juice, and thus it is most commonly used as orange flavoring. It can be produced by the reaction of butanoic acid with ethanol in the presence of an acid catalyst (H+H+): CH3CH2CH2CO2H(l)+CH2CH3OH(l)H+⟶CH3CH2CH2CO2CH2CH3(l)+H2O(l) Part A Given 7.30 gg of butanoic acid and excess ethanol, how many grams of ethyl butyrate would be synthesized, assuming a complete 100%% yield?
