Explanation:
(a) a functional group is a special group of atoms or bonds in a compound that is responsible for the chemical reactions, behavior, and characteristics of that compound. (b) Functional group is present in both the compound is alcohol (-OH).
Functional groups are specific groupings of atoms within molecules that have their own characteristic properties, regardless of the other atoms present in a molecule. Common examples are alcohols, amines, carboxylic acids, ketones, and ethers.
Key Points
Functional groups are often used to “functionalize” a compound, affording it different physical and chemical properties than it would have in its original form.
Functional groups will undergo the same type of reactions regardless of the compound of which they are a part; however, the presence of certain functional groups within close proximity can limit reactivity.
Functional groups can be used to distinguish similar compounds from each other.
Key Terms
functional group: A specific grouping of elements that is characteristic of a class of compounds, and determines some properties and reactions of that class.
functionalization: Addition of specific functional groups to afford the compound new, desirable properties.
Answer:
Option B. It is a basic solution.
Explanation:
To know which option is correct, let us calculate the pH of the solution.
First, we shall determine the pOH of the solution. This is illustrated below:
Concentration of Hydroxide ion, [OH¯] = 3.5×10¯⁶
pOH =.?
pOH = –Log [OH¯]
pOH = –Log 3.5×10¯⁶
pOH = 5.5
Finally, we shall determine the pH. This can be obtained as follow:
pOH = 5.5
pH =?
pH + pOH = 14
pH + 5.5 = 14
Collect like terms
pH = 14 – 5.5
pH = 8.5
The pH scale reads as follow:
0 to 6 => Acidic
7 => Neutral
8 to 14 => Basic
Comparing the pH of the solution (i.e 8.5) with the pH scale, we can conclude that the solution is basic because the pH of solution lies between 8 and 14.
I think you were doing it right. Just find something in your kitchen and google the chemical formula. And from that you can see the elements in it. For example:
Salt, NaCl, Sodium and Chlorine.
Baking Soda, NaHCO3, Sodium, Hydrogen, Carbon and Oxygen.
Vinegar, CH3COOH, Carbon, Hydrogen and Oxygen
Answer:
How Long Is The Lunar Cycle: Each lunar cycle lasts 27 days, 7 hours and 43 minutes. This means that the moon takes almost 28 days to complete a full orbit around the earth. Over this course, the moon goes through several phases, which alters its appearance and even the pattern of movement in the sky.

Lewis acid and Lewis base are most closely associated with ELECTRON TRANSFER.
A Lewis acid is any substance which can accept a pair of non bonding electron. A good example of a Lewis acid is hydrogen ion, H+. A Lewis base on the other hand is any specie which can donate a pair of electron. Thus, in Lewis theory of acid and base reaction, bases donate pairs of electrons and acids accept the pairs of electrons. Ammonia is a good example of a Lewis base.
