1. Замещение хлора на двойную связь#### Reactions for the Given Transformations

To achieve the transformations from CH2CL-CH2-CH3 to CH2двойная связCH-CH3 and then to CH3-CHBR-CH3, several reactions can be employed.

1. Conversion from CH2CL-CH2-CH3 to CH2двойная связCH-CH3: To convert CH2CL-CH2-CH3 to CH2двойная связCH-CH3, the following reaction can be used: - Elimination Reaction: This reaction involves the removal of a molecule from a larger molecule, resulting in the formation of a double bond. In this case, the elimination of a chlorine atom and a hydrogen atom from the given compound can lead to the formation of a double bond.

This transformation can be achieved through a process called dehydrohalogenation, which involves the removal of a hydrogen halide (such as HCl) to form a double bond. This can be carried out using a strong base like potassium hydroxide (KOH) or sodium hydroxide (NaOH) in an alcoholic solvent.

2. Conversion from CH2двойная связCH-CH3 to CH3-CHBR-CH3: To convert CH2двойная связCH-CH3 to CH3-CHBR-CH3, the following reaction can be used: - Addition Reaction: This reaction involves the addition of a molecule to a double bond, resulting in the formation of a new compound. In this case, the addition of a bromine atom to the double bond can lead to the formation of CH3-CHBR-CH3.

This transformation can be achieved through a process called electrophilic addition, where a bromine molecule adds across the double bond to form a dibromoalkane. This reaction can be carried out using a bromine (Br2) solution in an organic solvent.

By employing these reactions, the desired transformations from CH2CL-CH2-CH3 to CH2двойная связCH-CH3 and then to CH3-CHBR-CH3 can be achieved.
