JEE MAIN - Chemistry (2018 (Offline) - No. 13)
Consider the following reaction and statements:
[Co(NH3)4Br2]+ + Br- $$\to$$ [Co(NH3)3Br3] + NH3
(I) Two isomers are produced if the reactant complex ion is a cis-isomer
(II) Two isomers are produced if the reactant complex ion is a trans-isomer
(III) Only one isomer is produced if the reactant complex ion is a trans-isomer
(IV) Only one isomer is produced if the reactant complex ion is a cis – isomer
The correct statements are
[Co(NH3)4Br2]+ + Br- $$\to$$ [Co(NH3)3Br3] + NH3
(I) Two isomers are produced if the reactant complex ion is a cis-isomer
(II) Two isomers are produced if the reactant complex ion is a trans-isomer
(III) Only one isomer is produced if the reactant complex ion is a trans-isomer
(IV) Only one isomer is produced if the reactant complex ion is a cis – isomer
The correct statements are
(II) and (IV)
(I) and (II)
(I) and (III)
(III) and (IV)
설명
When reactant is cis isomer then following reaction takes place.
_en_13_1.png)
So, if reactant is cis - isomer then two isomers are produced.
When reactant is trans isomer then following reaction takes place.
_en_13_2.png)
So, if the reactant is trans isomer then only one isomer is produced.
So, if reactant is cis - isomer then two isomers are produced.
When reactant is trans isomer then following reaction takes place.
So, if the reactant is trans isomer then only one isomer is produced.
