Which member of each pair of compounds forms intermolecular H bonds? Draw the H-bonded structures in each case:
sveticcg [70]

FCH₂CH₂F will form Intermolecular Hydrogen bond

FCH₂CH₂F has H-F atoms linked together by Hydrogen bond whereas in HOCH₂CH₂OH here, carbon is linked with oxygen and oxygen is again linked with Hydrogen.

<h3>What is Intermolecular Hydrogen bond ?</h3>

Intermolecular hydrogen bonding refers to the formation of hydrogen bonds between molecules of the same or distinct substances. As an illustration, consider hydrogen bonds in water, alcohol, ammonia, etc.

  • An illustration. (i) hydrogen connection between the hydrogen fluoride molecules. (ii) The hydrogen bond in molecules of alcohol or water

  • Atoms within a molecule are held together by intramolecular forces. There are forces between molecules known as intermolecular forces.

a student is asked to prepare 75.0 ml of a 130M solution of HF using a 2.000M standard solution. Calculate the volume in mL of 2
Blizzard [7]

Answer:

Volume required from standard solution = 4675 mL

Explanation:

Given data:

Final volume = 75.0 mL

Final molarity = 130 M

Molarity of standard solution = 2.000 M

Volume required from standard solution = ?

Solution:

We use the formula,

C₁V₁ = C₂V₂

here,

C₁ = Molarity of standard solution

V₁ = Volume required from standard solution

C₂ = Final molarity

V₂ = Final volume

Now we will put the values in formula,

C₁V₁ = C₂V₂

2.000 M × V₁ = 130 M × 75.0 mL

V₁  = 9750 M. mL / 2.000 M

V₁  = 4675 mL
