How did organic compounds get their name and how is the word related to its meaning?

1 answer:

7 0

The molecules of organic compounds have carbon.
All living things are made up of organic compounds.
And the word "organic" refers to "life."

Rank the compounds in each set in order of increasing acid strength.

Viktor [21]

Answer:

See explanation

Explanation:

For this question, we have to remember the effect of an atom with high electronegativity as "Br". If the "Br" atom is closer to the carboxylic acid group (COOH) we will have an inductive effect. Due to the electronegativity of Br, the electrons of the C-H bond would be to the Br, then this bond would be weaker and the compound will be more acid (because is easier to produce the hydronium ion $H^+$ ).

With this in mind, for A in the last compound, we have 2 Br atoms near to the acid carboxylic group, so, we will have a high inductive effect, then the C-H would be weaker and we will have more acidity. Then we will have the compound with only 1 Br atom and finally, the last compound would be the one without Br atoms.

In B, the difference between the molecules is the position of the "Br" atom in the molecule. If the Br atom is closer to the acid group we will have a higher inductive effect and more acidity.

See figure 1

When a sodium atom becomes an ion the size of the atom?

jeyben [28]

The size of atom reduces

Electronic configuration of sodium -

C6H12O6 + 6 O2 --> 6 CO2 + 6 H2O + energy In the reaction listed above, 1 molecule of glucose reacts with 6 molecules of oxyg

kirill115 [55]

Answer:

Third choice: energy present in the glucose and oxygen that is not needed for the formation of carbon dioxide and water is released to form energy/ATP.

Explanation:

1) Chemical equation (given):

C₆H₁₂O₆ + 6 O₂ --> 6 CO₂ + 6 H₂O + energy

2) Chemical potential energy:

Each compound stores chemical potential energy. This energy is stored in the chemical bonds.

Due to every substance has its own unique chemical potential energy, when a chemical reaction takes plase, yielding to the change of some substances, some energy is absorbed (when bonds are formed) and some energy is released (when bonds are broken).

3) Conservation of energy:

Then, if the sum of the bond energies of the final products is less than the sum of the bond energies of the reactants, the law of conservation of energy rules that the difference between the total energies of the products and reactants must be released to the surroundings.

That is what is happening in the given reaction:

C₆H₁₂O₆ + 6 O₂ --> 6 CO₂ + 6 H₂O + energy

The term energy in the product side means that energy is conserved because it is being released due to the the glucose and oxygen (reactant side) have more energy stored in their bonds than the energy needed for the formation of carbon dioxide and water, so that excess of energy is released to form energy/ATP.

Summarizing:

The energy on the product side added to the energy of carbon dioxide and water equals the energy of the glucose and oxygen and the final balance is:

∑ Energy of the reactants = ∑energy of the products + released energy, supporting the law of conservation of energy.
