Question

A)CH2=CH2+HCl-> B)CH3-CH3 t,kat-> C)CH=CH2+Cl2-> D)CH2=CH2+H2->

Answer 1

Ответ:

A)CH2=CH2+HCl->CH3CH2Cl

B)CH3-CH3 t,kat->CH2=CH2

C)CH2=CH2+Cl2->CH2ClCH2Cl

D)CH2=CH2+H2->CH3-CH3

Answer 2

A) The reaction between CH2=CH2 (ethylene) and HCl (hydrochloric acid) results in the formation of CH3-CH2-Cl (ethyl chloride). This is an example of an addition reaction where the double bond in ethylene is broken, and a chlorine atom replaces one of the hydrogen atoms.

B) It seems you have provided "t,kat" after the reaction equation. "t" usually represents time, and "kat" might refer to a catalyst. However, the provided information is not sufficient to determine the specific conditions or catalyst involved in the reaction. The reaction equation CH3-CH3 could refer to the formation of ethane, which is the simplest alkane composed of two carbon atoms bonded to each other and surrounded by hydrogen atoms.

C) The reaction between CH=CH2 (ethylene) and Cl2 (chlorine) results in the formation of CH2Cl-CH2Cl (1,2-dichloroethane). This is an example of an addition reaction where the double bond in ethylene is broken, and two chlorine atoms replace the hydrogen atoms.

D) The reaction between CH2=CH2 (ethylene) and H2 (hydrogen gas) under suitable conditions (such as high temperature and the presence of a suitable catalyst) can result in the formation of CH3-CH3 (ethane). This is an example of a hydrogenation reaction where the double bond in ethylene is saturated with hydrogen atoms, resulting in the formation of a single bond between the carbon atoms.
