Ionic or covalent C2H5OH
Afina-wow [57]

Answer:

Covalent  

Explanation:

A molecule of C₂H₅OH has C-C, C-H, C-O, and O-H bonds.

A bond between A and B will be ionic if the difference between their electronegativities (ΔEN) is greater than 1.6.

\begin{array}{ccc}\textbf{Bond} & \textbf{$\Delta$EN} & \textbf{Polarity}\\\text{C-C} & 2.55 - 2.55 = 0.00 & \text{Nonpolar covalent}\\\text{C-H} & 2.55 - 2.20 = 0.35 & \text{Nonpolar covalent}\\\text{C-O} & 3.44 - 2.55 = 0.89 & \text{Polar covalent}\\\text{O-H} & 3.44 - 2.20 = 1.24 & \text{Polar covalent}\\\end{array}

No bond has a large enough ΔEN to be ionic.

C₂H₅OH is a covalent molecule.

When looking at Newman projections are there instances where the staggered confirmation is not the lowest in energy? Explain you
stiks02 [169]

Answer:

let's summarize the caution as we are given with human projection. We have to tell them stances where staggered confirmation is not the lowest in energy. Okay, so let's see that. Are there any instances that which conforms tiger is not the lowest energy. Okay, so the lowest energy is what then happened? The lowest in energy already happens on living. Honestly, when, when it happens the lowest in energy only happens when the bulky groups are at 1 80 degree with each other. When it happens when bulky, bulky, bulky groups are at 1 80 degree. Okay, When they are, for example, when the bulky groups are in this way At 180°, then it is Louis Why? Because repulsion are very less repulsion very less. Got it. So we have to tell when it is not the lowest so far not the lowest instance. These bulky groups should be together. So if they either make of angle of 60° or 300° together, suppose this is a bulky group one and this is a bulky group two and okay, so if it makes a 60 degree or 300 degree then this um have the highest energy Or has the energy is not lowest in it. Why? It is not lowest in it Because at 300° or 60°. Why? Because the pulsations are very high repulsion. Are you ready? Hi. So by looking at the humans projection we can conclude that when the if the bulky group parrot 1, 80 degree be considered as the lowest energy. And if they are at 300 or 60 degree or close to each other, republicans are higher and they are not in lowest energy.

In the simulation, open the Micro mode, then select solutions indicated below from the dropdown above the beaker in the simulati
Levart [38]

Explanation:

It is known that when pH of a substance is more than 7 then the substance is considered basic in nature. When pH of a substance is less than 7 then the substance is considered acidic in nature.

And, when the pH of a substance is equal to 7 then it is considered neutral in nature.

The pH of given substances are as follows.

Coffee = 5.0

Orange Juice = 3.5

Milk = 6.5

Soda pop = 2.5

Battery acid = 1.0

As battery acid as very low pH therefore, it is highly acidic in nature.

Thus, we can conclude that given acids are arranged in increasing order of acidity as follows.

          Milk < Coffee < Orange juice < Soda pop < Battery acid
