Answer:
The correct answer is: alcohol (C-OH) functional group
Explanation:
Electronegativity is described as the ability or the tendency of an element to attract the electron density or shared bonding electrons towards itself.
The electronegativity value of oxygen atom, nitrogen atom and, carbon atom is 3.44, 3.04, and 2.55.
From this data we can conclude that oxygen is more electronegative than nitrogen. Also, the electronegativity difference of oxygen and carbon (0.89) is greater than the electronegativity difference of nitrogen and carbon (0.49).
Therefore, <u>the</u><u> electronegativity </u><u>of the oxygen containing </u><u>alcohol</u><u> functional group (C-OH) will be greater than the electronegativity of the nitrogen (C-NH) containing amine functional group.</u>
<u>Answer:</u> The correct answer is Option A, Option B and Option D.
<u>Explanation:</u>
Molecular compound are defined as the compounds which are formed by the sharing of electrons between the atoms. They are also known as covalent compounds. They are of two types:
- <u>Polar covalent compound:</u> This compound is formed when difference in electronegativity between the atoms is present. When atoms of different elements combine, it results in the formation of polar covalent bond. For Example:
etc.. - <u>Non-polar covalent compound:</u> This compound is formed when there is no difference in electronegativity between the atoms. When atoms of the same element combine, it results in the formation of non-polar covalent bond. For Example:
etc..
We know that: Like dissolves like. This means that polar solvent will dissolve polar molecules and non-polar solvent will dissolve non-polar molecules
Water is a polar compound. So, it will dissolve only polar molecules.
The given substance 'X' is a molecular compound. It may be polar or non-polar.
So, it may be soluble in water or may not be soluble.
Electrolyte are defined as the compound which conduct electricity when dissolved in water. They conduct electricity because of the ions they dissociate into.
Thus, substance 'X' is not an electrolyte.
Hence, the correct answer is Option A, Option B and Option D.
Answer:
A) is true
Explanation:
For the reaction:
O₂(g) + 2F₂(g) ⇄ 2OF₂(g); Kp = 2,3x10⁻¹⁵
kp is defined as:
Kp = 2,3x10⁻¹⁵ = [OF₂]²/[O₂] [F₂]²
A) If the reaction mixture initially contains only OF₂(g), then at equilibrium, the reaction mixture will consist of essentially only O₂(g) and F₂(g). <em>TRUE. </em>As the kp is 2,3x10⁻¹⁵ means per 1 of [O₂] [F₂]² you will have just 2,3x10⁻¹⁵ of [OF₂]²
B) For this equilibrium, Kc = Kp. <em>FALSE. </em>That is true just when moles of reactants are the same than moles of products. Here there are 3 moles of reactants vs 2 moles of products.
C) If the reaction mixture initially contains only OF₂(g), then the total pressure at equilibrium will be less than the total initial pressure. <em>FALSE. </em>Because per 2 moles of OF₂(g) you will produce 3 moles of gas increasing pressure.
D) If the reaction mixture initially contains only O₂(g) and F₂(g), then at equilibrium, the reaction mixture will consist of essentially only OF₂(g). <em>FALSE. </em>For the same reason of A), the mixture will contains essentially only O₂(g) and F₂(g)
E) If the reaction mixture initially contains only O₂(g) and F₂(g), then the total pressure at equilibrium will be greater than the total initial pressure. <em>FALSE. </em>If mixture initially contains only O₂(g) and F₂(g), 3 moles will of gas will react to produce 2 moles of gas doing pressure decreases.
