Answer from: Maaarii

(a) 3-bromo-1-chlorobutane

(b) 2-bromo-1-chlorobutane

(d) 1,1,2,2-tetrachloropropane

(e) 1-ethylcyclopentan-1-ol

Explanation:

We can analyze each reaction:

(a) 4-Chlorobut-1-ene + HBr

In this reaction, we have an alkene. So, we will have an addition reaction, the nucleophile " Br^- " will be added to the most substituted carbon. In this case carbon 3 to produce 3-bromo-1-chlorobutane.

(b) 1-Chlorobut-1-ene + HBr

In this reaction, we also have an alkene. So, we will have an addition reaction, the nucleophile " Br^- " will be added to the most substituted carbon. In this case carbon 2 to produce 2-bromo-1-chlorobutane.

In this reaction, we have an alkene. So, we will have an addition reaction, the nucleophile " H_2O " will be added to the most substituted carbon. In this case carbon 3 to produce 3,3-dimethylcyclopentan-1-ol.

(d) Propyne + 2HCl

In this reaction, we have an alkyne. So, we will have an addition reaction, the nucleophile " Cl^- " will be added to the most substituted carbon, but we have 2 moles of the nucleophile, so would be added 2 times and we will have as product 1,1,2,2-tetrachloropropane.

(e) Cyclopentylethene + H3O+

In this reaction, we have an alkene. So, we will have an addition reaction, the nucleophile " H_3O^+ " will be added to the most substituted carbon. But in this case, the carbon cation would be produced in carbon 1 of the ethene. So, we can have a hydride shift to produce a tertiary carbocation. With this in mind the nucleohile will be addde to this tertiary carbocation and we will have 1-ethylcyclopentan-1-ol.
