A reaction in which two ions switch places is which type of reaction?
AURORKA [14]

A reaction in which two ions switch places is called double-displacement reaction.

Explanation:

Double displacement reaction usually takes place between two positive ions or two negative ions. When anions or cations of totally different compounds change places, two totally different compounds are formed.  

<u>Syntax for double displacement reaction: </u>

AB + CD --> AD + BC

It can also be defined in simple terms as the reaction in which exchange of ions takes place is called double displacement reaction.

The chemical reaction is as follows:

NaOH(aq) + HCl(aq)  --> NaCl(aq)  + H2O (l)

In each reaction box, place the best reagent and conditions from the list below.
Serggg [28]
This is a two step step reaction as shown below,

Step 1:
           Epoxidation of Alkene:
                                              In first step Cyclohexene is treated with peroxybenzoic acid in the presence of Dichloromethane which results in the formation of epoxide moiety.

Step 2:
           Nucleophillic Substitution Reaction:
                                                                  In second step the epoxide formed is treated with Sodium Methoxide which acts as a nucleophile and attacks the less hindered carbon of epoxide resulting in the formation of final product as shown below.
