How many secondary alcohol groups are present in glucose?
In glucose we have five alcohol groups (−OH) and one aldehyde group (R−H|C=O). In fructose also we have five alcohol groups but one ketone group (R−R|C=O), where R group is a chain of carbon atoms or one carbon atom.
How many 2 degree alcoholic groups are present in open chain structure of glucose?
It contains one aldehyde (-CHO) group, one primary alcoholic (-CH2OH) group and four secondary alcoholic (-CHOH) groups.
How many groups are present in the open structure of glucose?
Glucose is a monosaccharide containing six carbon atoms and an aldehyde group, and is therefore an aldohexose. The glucose molecule can exist in an open-chain (acyclic) as well as ring (cyclic) form….Glucose.

How much secondary alcohol is in fructose?
It is bifunctional compound i.e. its molecule possesses one aldehyde group and five hydroxyl groups is primary and rest four are secondary in nature.
How many primary and secondary alcoholic groups are present in glycerol?
The molecule of glycerol contains two primary alcoholic (-OH) group and one secondary alcoholic (-OH) group hence it shows characteristics of both primary and secondary alcohols.
Does glucose have a carbonyl group?
In glucose and galactose, the carbonyl group is on the C1 carbon, forming an aldehyde group. In fructose, the carbonyl group is on the C2 carbon, forming a ketone group. The former sugars are called aldoses based on the aldehyde group that is formed; the latter is designated as a ketose based on the ketone group.
How many primary alcohols are in glucose?
It has one primary alcoholic group which is at the sixth carbon atom.
What is the number of primary alcoholic group in glucose *?
Glucose gives a penta ester with acetic anhydride, revealing that it has 5 hydroxyl groups. On oxidation with Nitric acid (HNO3),glucose as well as gluconic acid both yeild a dicarboxylic acid (saccharic acid).
How many secondary carbon atoms are there in the structure of glucose?
6 carbons
Therefore, all 6 carbons are secondary.
How many alcoholic groups are present in glycerol?
Which of the following is secondary alcohol?
The secondary alcohol is 2-pentanol, i.e. propan-2-ol.
How many chiral carbons are present in glucose?
four chiral carbons
Glucose has four chiral carbons in its aldehyde form, and so there are 24, or 16 possible stereoisomers of this formula, only one of which is dextrose [(+)-glucose].
Is glucose a secondary alcohol in the open structure?
This is an unrealistic question because glucose does not exist in the open structure exists only in the cyclical form which is sometimes called the book form or chair form. Thus it is immaterial in this cyclical form which alcohol groups are secondary alcohols.
How to draw open chain structure of a glucose molecule?
1. Steps to Draw Open Chain Structure of a Glucose Molecule. Follow the steps given below to draw an acyclic form of glucose. Step 1: Draw 6 carbon atoms. Step 2: Draw extended arms for all the carbon atoms excluding the first one. Step 3: Now draw hydrogen to carbon bond such that four are on one side and one on the other side.
What is the structure of the aldehydic group in glucose?
In the open chain form, glucose has an aldehydic group (on C1), secondary alcoholic groups (on C2–5) and a primary alcoholic group (on C6). When the molecule cyclises, the aldehydic group reacts with the alcoholic group on C5 to produce a six membered ring and to generate the hemicetal function on C1.
What is the structure of DDD-glucose?
D-Glucose. Glucose is a monosaccharide containing six carbon atoms and an aldehyde group and is therefore referred to as an aldohexose. The glucose molecule can exist in an open-chain (acyclic) and ring (cyclic) form, the latter being the result of an intramolecular reaction between the aldehyde C atom and the C-5 hydroxyl group to form an…
