Answer:
Structure is attached.
Explanation:
It is quite simple. The parent compound is benzaldehyde which is a benzene containing CHO functional group.
Now, starting numbering from CHO put methoxy (-OCH₃) groups at position 3 and 5.

Answer:
1. The empirical formula is C₄H₅N₂O
2. The molecular formula is C₈H₁₀N₄O₂
Explanation:
The following data were obtained from the question:
Mass of compound = 200 g
Carbon (C) = 98.061 g
Hydrogen (H) = 10.381 g
Oxygen (O) = 32.956 g
Empirical formula =?
Molecular formula =?
Next, we shall determine the mass of nitrogen in the compound. This can be obtained as follow:
Nitrogen (N) = 200 – (98.061 + 10.381 + 32.956)
Nitrogen (N) = 200 – 141.398
Nitrogen (N) = 58.602 g
1. Determination of the empirical formula of the compound.
C = 98.061 g
H = 10.381 g
O = 32.956 g
N = 58.602 g
Divide by their molar masses
C = 98.061 /12 = 8.172
H = 10.381 /1 = 10.381
O = 32.956 /16 = 2.060
N = 58.602 /14 = 4.186
Divide by the smallest
C = 8.172 /2.060 = 4
H = 10.381 / 2.060 = 5
O = 2.060 / 2.060 = 1
N = 4.186 / 2.060 = 2
Thus, the empirical formula of the compound is C₄H₅N₂O
2. Determination of the molecular formula of the compound.
Empirical formula of the compound => C₄H₅N₂O
Molar mass of compound = 194.101 g/mol
Molecular formula =.?
[C₄H₅N₂O]n = 194.101
[(12×4) + (1×5) + (14×2) + 16]n = 194.101
[48 + 5 + 28 + 16]n = 194.101
97n = 194.101
Divide both side by 97
n = 194.101 /97
n = 2
Molecular formula => [C₄H₅N₂O]n
=> [C₄H₅N₂O]2
=> C₈H₁₀N₄O₂
Answers
Answer: Option (c) is the correct answer.
Explanation:
Entropy is defined as the degree of randomness that is present within the particles of a substance.
As is ionic in nature. Hence, when it is added to water then it will readily dissociate into ammonium ions (
) and nitrate ions (
).
Therefore, it means that ions of ammonium nitrate will be free to move from one place to another. Hence, there will occur an increase in entropy.
Thus, we can conclude that ammonium nitrate () dissolve readily in water even though the dissolution process is endothermic by 26.4 kJ/mol because the overall entropy of the system increases upon dissolution of this strong electrolyte.

Answer:
Explanation:
BrCl₃ is an interhalogen compound with a hybridization of sp³d. The approximate bond angles can be predicted from the structure (attached below). Although, the lewis structure might be predicted to be trigonal bipyramidal from the structure, it is however a T-shaped geometry because of it's two lone pairs.
Also, from the structure attached, it can be predicted that the approximate bond angles about the central atom is 120° (360 ÷ 3) since each of the three chlorine atoms is equally spaced about the central atom.
The Lewis structure for BrCl₃ is attached to the image below. The bond angles around the central atom, bromine (Br), are 90 degrees between the bromine and each chlorine atom. Therefore, option B is correct.
A Lewis structure, also known as an electron-dot structure or Lewis dot structure is a diagram that represents the valence electrons of an atom or molecule.
Bromine (Br) is in Group 7A and has 7 valence electrons, while each chlorine (Cl) atom in Group 7A also has 7 valence electrons.
Br: 1 atom × 7 valence electrons = 7 valence electrons
Cl: 3 atoms × 7 valence electrons = 21 valence electrons
Total valence electrons = 7 + 21 = 28
