Answer:
The Fischer Projection formula of D-glucose is as shown in the attachment below.
The chiral centre that determines its name is the last carbon from the carbonyl group, C-6
Explanation:
Fisher projection formulas are used to show sugars in their open chain form. In a Fischer projection, the carbon atoms of a sugar molecule are joined vertically by solid lines, while carbon-oxygen and carbon-hydrogen bonds are joined horizontally using solid lines as well.
The horizontal bonds project out of the plane of the paper or screen towards the reader whereas vertical bonds project behind the plane of the paper or screen, away from the reader.
Glucose is an aldose sugar with two different optical isomers or enantiomers, D-glucose and L-glucose. The designation D- or L- depends on the configuration of the chiral or asymmetric carbon most distant from the carbonyl carbon of glucose. If the chiral carbon has the same configuration as D-glyceraldehyde, that the -OH roup on the right side of the carbon and -H group on the left, it is snamed D-glucose. However, if the chiral carbon has the same configuration as L-glyceraldyde, that is with the -OH group on the right and the -H group on the right, it is named L-glucose
Answer:
Option 4) equal to
Explanation
When having a reversible reaction, this reaction (or system) reaches the balnace, it is observed that relative quantitives for all compounds (this is, reactives and products), remain constant
The species concentration does not change over time, and; in the same way; there are no physical changes as time goes by
For example, for the following reaction :
aA + bB ⇔ cC + dD
Compounds A and B react to give products C and D. The two way arrows means that this systme has reached the balance (is in equilibrium)
Reaction type : Double-Replacement reactions
<h3>Further explanation</h3>
Given
Reaction
MgCl2 +
Li2CO3 →
MgCO3 +
LiCl
Required
Balanced equation
Reaction type
Solution
Balanced equation
Li2CO3 (s) + MgCl2 (aq) → MgCO3 (s) + 2 LiCl (aq)
Double-Replacement reactions. Happens if there is an ion exchange between two ion compounds in the reactant to form two new ion compounds in the product
To predict whether this reaction can occur or not is one of them, the precipitation reaction.
MgCO3 is a precipitation compound
