What products are formed when zinc reacts with(i) Vicinal C2H4Br2 and (ii) CH3CHBr – CH2Br

(i) When zinc reacts with vicinal C2H4Br2 (1,2-dibromoethane), it forms an organozinc compound known as ethylenezinc bromide (C2H4ZnBr2). This reaction is a type of organometallic synthesis.

Here's the reaction:

C2H4Br2 + Zn → C2H4ZnBr2

(ii) When zinc reacts with CH3CHBr-CH2Br (1,2-dibromopropane), it forms propylenezinc bromide (C3H6ZnBr2). This is also an organometallic synthesis.

Here's the reaction:

CH3CHBr-CH2Br + Zn → C3H6ZnBr2

In both reactions, the zinc replaces the bromine atoms, forming a bond with the carbon atoms.

(i) When zinc reacts with vicinal C2H4Br2 (1,2-dibromoethane), it forms an organozinc compound known as ethylenezinc bromide (C2H4ZnBr2). This reaction is a type of organometallic synthesis.

Here's the step-by-step reaction:

1. Zn + C2H4Br2 → C2H4ZnBr2

(ii) When zinc reacts with CH3CHBr – CH2Br (1,2-dibromopropane), it forms an organozinc compound known as propylenezinc bromide (C3H6ZnBr2).

Here's the step-by-step reaction:

1. Zn + CH3CHBr – CH2Br → C3H6ZnBr2

In both reactions, the zinc atom replaces the bromine atoms in the organic compounds, forming new organozinc compounds.
