Question

Встановіть відповідність між реагентами та продуктами реакцій. 1) CH2 = CH2+ Br2->; 2)CH=CH+H2 >- 3) CH4 + Cl2>; 4)CH4 >-. A) CH2 = CH2; Б)CH2,Br-CH2Br; B) C+2H2; Г) CH3,CI +HCI; Д) СНз - СНз.

Answer 1

CH2 = CH2 + Br2 -> Б) CH2Br-CH2Br
CH=CH + H2 -> Д) CH3-CH3
CH4 + Cl2 -> Г) CH3Cl + HCl
CH4 -> A) CH4
Отже, відповідності між реагентами та продуктами реакцій:

Б
Д
Г
А

Answer 2

Matching Reagents and Products

To match the reagents and products in the given reactions, let's analyze each reaction one by one:

1) CH2 = CH2 + Br2 -> - Reagent: CH2 = CH2 (ethylene) - Product: Br-CH2-CH2-Br (1,2-dibromoethane) [[1]]

2) CH = CH + H2 -> - Reagent: CH = CH (ethylene) - Product: CH3-CH3 (ethane) [[2]]

3) CH4 + Cl2 -> - Reagent: CH4 (methane) - Product: CH3Cl (chloromethane) [[3]]

4) CH4 -> - Reagent: CH4 (methane) - Product: No specific product is mentioned. It could be any product formed from the decomposition of methane.

Matching the reagents and products to the given options:

A) CH2 = CH2; - Matches with reaction 1) CH2 = CH2 + Br2 -> Br-CH2-CH2-Br (1,2-dibromoethane)

B) CH2,Br-CH2Br; - Does not match with any of the given reactions.

C) C2H2; - Does not match with any of the given reactions.

D) CH3,CI+HCI; - Does not match with any of the given reactions.

Therefore, the correct matching is: A) CH2 = CH2 -> 1) CH2 = CH2 + Br2 -> Br-CH2-CH2-Br (1,2-dibromoethane)
