Answer:
a) Both chairs conformers have one of its substituents in an axial position and the other in an equatorial position
b) One chair conformer has both its substituents in an axial position while the other chair has its substituents in an equatorial position
c) One chair conformer has both its substituents in an axial position while the other chair has its substituents in an equatorial position
d) Both chairs have one of its substituents in an axial position and the other in an equatorial position
e) Both chairs have one of its substituents in an axial position and the other in an equatorial position
(f) One chair conformer has both its substituents in an axial position while the other chair has its substituents in an equatorial position
Explanation:
Determine what the substituents would be
a) Cis-1,2- : Both chairs conformers have one of its substituents in an axial position and the other in an equatorial position
b) Trans-1,2- : One chair conformer has both its substituents in an axial position while the other chair has its substituents in an equatorial position
c) Cis-1,3- : One chair conformer has both its substituents in an axial position while the other chair has its substituents in an equatorial position
d) Trans-1,3- : Both chairs have one of its substituents in an axial position and the other in an equatorial position
e) Cis-1,4- : Both chairs have one of its substituents in an axial position and the other in an equatorial position
(f) Trans-1,4- : One chair conformer has both its substituents in an axial position while the other chair has its substituents in an equatorial position
Answer: The correct formula is
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
Here magnesium is having an oxidation state of +2 called as cation and bromine
is an anion with oxidation state of -1. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral
.
The cations and anions being oppositely charged attract each other through strong coloumbic forces and form an ionic bond.
