(a)
Interpretation:
The cation derived from Lithium & the Nitrite anion should be combined in order to get an electrically neutralized ionic compound.
Concept introduction:
An ionic compound forms by the mutual attraction of 2 oppositely charged ions called cation & anion. Cation is derived from Lithium (Li). Anion is Nitrite (NO2-), which is a polyatomic anion. It is a combination of Nitrogen & Oxygen, working as a single unit.
(b)
Interpretation:
The cation derived from Calcium & the Acetate anion should be combined in order to get an electrically neutralized ionic compound.
Concept introduction:
An ionic compound forms by the mutual attraction of 2 oppositely charged ions called cation & anion. Cation is derived from Calcium (Ca). Anion is Acetate (CH3COO-), which is a polyatomic anion. It is a combination of Carbon, Hydrogen& Oxygen, working as a single unit.
(c)
Interpretation:
The cation derived from Sodium& the Bisulfite anion should be combined in order to get an electrically neutralized ionic compound.
Concept introduction:
An ionic compound forms by the mutual attraction of 2 oppositely charged ions called cation & anion. Cation is derived from Sodium (Na). Anion is Bisulfite (HSO3-), which is a polyatomic anion. It is a combination of Hydrogen, Sulfur& Oxygen, working as a single unit.
(d)
Interpretation:
The cation derived from Manganese& the Phosphate anion should be combined in order to get an electrically neutralized ionic compound.
Concept introduction:
An ionic compound forms by the mutual attraction of 2 oppositely charged ions called cation & anion. Cation is derived from Manganese (Mn). Anion is Phosphate (PO43-), which is a polyatomic anion. It is a combination of Phosphorous& Oxygen, working as a single unit.
(e)
Interpretation:
The cation derived from Magnesium& the Hydrogen sulfite anion should be combined in order to get an electrically neutralized ionic compound.
Concept introduction:
An ionic compound forms by the mutual attraction of 2 oppositely charged ions called cation & anion. Cation is derived from Magnesium (Mg). Anion is Hydrogen sulfite (HSO3-), which is a polyatomic anion. It is a combination of Hydrogen, Sulfur& Oxygen, working as a single unit.

- 3. Consider the compounds below and determine if they are aromatic, antiaromatic, or non-aromatic. In case of aromatic or anti-aromatic, please indicate number of I electrons in the respective systems. (Hint: 1. Not all lone pair electrons were explicitly drawn and you should be able to tell that the bonding electrons and lone pair electrons should reside in which hybridized atomic orbital 2. You should consider ring strain- flexibility and steric repulsion that facilitates adoption of aromaticity or avoidance of anti- aromaticity) H H N N: NH2 N Aromaticity (Circle) Aromatic Aromatic Aromatic Aromatic Aromatic Antiaromatic Antiaromatic Antiaromatic Antiaromatic Antiaromatic nonaromatic nonaromatic nonaromatic nonaromatic nonaromatic aromatic TT electrons Me H Me Aromaticity (Circle) Aromatic Aromatic Aromatic Aromatic Aromatic Antiaromatic Antiaromatic Antiaromatic Antiaromatic Antiaromatic nonaromatic nonaromatic nonaromatic nonaromatic nonaromatic aromatic πT electrons H HH…arrow_forwardA chemistry graduate student is studying the rate of this reaction: 2 HI (g) →H2(g) +12(g) She fills a reaction vessel with HI and measures its concentration as the reaction proceeds: time (minutes) [IH] 0 0.800M 1.0 0.301 M 2.0 0.185 M 3.0 0.134M 4.0 0.105 M Use this data to answer the following questions.
