Answer:

If a solid line represents a covalent bond and a dotted line represents intermolecular attraction, which of the choices shows a hydrogen bond?

-N-------H-O-

-O------H-C-

-C-----H-F-

H-H

Of the options shown those that form hydrogen bonds are the following:

-N-------H-O-

-O------H-C-

Since they occur from the attraction in a hydrogen atom and an oxygen or nitrogen atom with a negative charge.

Explanation:

The hydrogen bridge or hydrogen bond force is the attractive electrostatic force between an electronegative atom and a hydrogen atom covalently bonded to another electronegative atom. It results from the formation of a charge-dipole force with a hydrogen atom attached to a nitrogen, oxygen or fluorine atom.

The hydrogen bond strength is located somewhere between a covalent bond and a Van der Waals force (dispersion force). This type of bonding occurs both in inorganic molecules such as water, and in organic molecules such as DNA.

How does the formal charge play a role in resonance?
Crank
In a Lewis structure, formal charges can be assigned to each atom by treating each bond as if one-half of the electrons are assigned to each atom. ... Resonance occurs in cases where two or more Lewis structures with identical arrangements of atoms but different distributions of electrons can be written.

uysha [10]

Explanation:

Steps followed to practice laboratory safety during the experiment are as follows.

  • Used tongs or a test tube holder to hold materials over the Bunsen burner flame.
  • Wore gloves and goggles.
  • Made careful observations of the products and reactants.
  • Did not smell the gases produced.

When we heat a test tube over bunsen flame then the tube gets hot and when we hold it with bare hands then out hands will burn. Therefore, it is advised to hold test tube with the help of tongs or a holder so that our hands did not burn.

We should also wear gloves and goggles so that any acid would not spill directly on our hands, skin and eyes as it can affect or damage the skin severely.

Careful observations were made so that correct calculations about the experiment can be carried out.

It is also advised that we should not smell the gases produced but gases move freely from one place to another in a laboratory or any where else.

So, we can try to avoid it by covering our mouth with a cloth but we cannot stop it. If we keep on inhaling the gases produced in a laboratory then it can also lead to severe disease or defect in the human body.
