Identify the compound that would have the highest osmotic pressure when dissolved in water. nacl k2so4 mgcl2 fecl3 mgso4
brilliants [131]

The compound that would have the highest osmotic pressure when dissolved in water is FeCl_{3} .

So,  option D is correct one.

The dissociation of one molecule of  FeCl_{3} gives the maximum number of ions when dissolved in water ( 4 ions ) . Osmotic pressure is a colligative property and depends upon number of solute particles present in the solution . The solution having maximum number of solute particles will have maximum number of the osmotic pressure .

All other given molecules gives less number of number of ions when dissolved in water as compare to of  FeCl_{3} .

WILL GIVE BRANLIEST TO FIRST ANSWER!!! I know the correct answer is either a or d. Can anyone explain which one it is and why? C
oee [108]

Answer: The IUPAC name of CH_3C\equiv CCH_2CH_2Cl is 5-chloro-2-pentyne

Explanation:

1. First select the longest possible carbon chain.  For the number of carbon atom, we add prefix as 'meth' for 1, 'eth' for 2, 'prop' for 3, 'but' for 4, 'pent' for 5, 'hex' for 6, 'sept' for 7, 'oct' for 8, 'nona' for 9 and 'deca' for 10.

2. The longest possible carbon chain should contain all the bonds and functional groups.

3. The numbering is done in such a way that the carbon containing the functional group or substituent gets the lowest number. Triple bond is given priority over substituent halogen.

4. The naming of alkane is done by adding the suffix -ane, alkene by adding the suffix -ene, alkyne.

Thus the IUPAC name of CH_3C\equiv CCH_2CH_2Cl is 5-chloro-2-pentyne

What is the relationship between nucleic acids and nucleotides?
maw [93]

The nucleotides are monomers of nucleic acid.

The nucleic acids are the macro molecules. They are two types- DNA and RNA. The nucleic acid, DNA consists of nucleotide which are monomers of the DNA. The nucleotides have three components such as pentose sugar, nitrogen bases, and phosphate.

They are the backbone of DNA. DNA is the polymer of nucleotide, and this DNA is coming under nucleic acids. The nucleotides form DNA, and DNA forms the nucleic acid. They are interlinked with each other.

Nucleic acids are the center for storing all the information. The deoxyribose nucleic acid or DNA is the center for storing all the genetic information.

The genetic material is inherited from the parents to the children. The characters are transferred from one generation to another.

The characters such as hair color, hair type, eye color are some of the genetic information that is carried from one generation to another via nucleic acids.

Nucleotide is the basic unit of nucleic acid (DNA and RNA) which store the genetic code of the cell.

It consists of sugar base (ribose or deoxyribose), nitrogenous base (A, T, G, C and U), and phosphate group.

Nucleotides (specially ATP) provides the energy for most of the cellular processes.

Therefore, with the above statements we got to know that both nucleic acid and nucleotides are genetically modified.
