How many chiral centers does clavulanic acid have?
VikaD [51]

Answer:

Clavulanic acid has two (2) chiral centers.

Explanation:

A chiral center is a center (usually carbon) with four different substituents.

The structure of clavulanic acid is shown in the attachment below.

Consider the labeled diagram in the attachment,

Carbon A is not a chiral carbon because it has two hydrogen atoms attached to it

Carbon B is not a chiral carbon because it has only three substituents

Carbon C is a chiral carbon because it has four different substituents

Carbon D is a chiral carbon because it has four different substituents

Carbon E is not a chiral carbon because it has only three atoms directly attached to it

Carbon F is not a chiral carbon because it has only three atoms directly attached to it

Carbon G is not a chiral carbon because it has two hydrogen atoms attached to it

Carbon H is not a chiral carbon because it has only three substituents

Then, only carbons C and D are chiral carbons.

Hence, clavulanic acid have two (2) chiral centers.

The compound, nah2po4, is present in many baking powders. what is its name? sodium phosphate sodium bephosphate sodium dihydroge
AlladinOne [14]
 The  compound NaH2PO4     name  is

sodium  dihydrogen  phosphate

 
Explanation
This name is    arrived  at  by using the   IUPAC rules  of naming   compound

1.  the metal (sodium)is  named  first  followed  by  the ligand ( hydrogen  and phosphate)

Ligand  are  molecules   that are   attached to  the metal  center.

2.   ligand  are  named using alphabetical   order(for  our  case  h  for hydrogen come before p for  phosphate hence hydrogen is named first)

3. Prefix   di is used  since hydrogen  are two

hence the name  of the compound  is  Sodium dihydrogen  phosphate
