CH3-CH=CH2-HCL CH4+CL2- CH2=CH-CH2-CH3+H2 химев-ва УВ
It looks like you're presenting a series of chemical reactions involving hydrocarbons and their reactions with hydrochloric acid (HCl), chlorine (Cl2), and possibly hydrogen (H2). Let’s break down each of the reactions you've mentioned:
Propene and HCl: The first reaction appears to involve propene (CH3-CH=CH2) reacting with hydrochloric acid (HCl). This is an electrophilic addition reaction where HCl adds across the double bond:
\[ \text{CH}_3\text{CH}=\text{CH}_2 + \text{HCl} \rightarrow \text{CH}_3\text{CHClCH}_3 \]
This product is 2-chloropropane.
Methane and Chlorine: The second reaction seems to refer to the chlorination of methane (CH4) with chlorine (Cl2). This is a free radical substitution reaction that typically requires UV light to initiate:
\[ \text{CH}_4 + \text{Cl}_2 \xrightarrow{UV} \text{CH}_3\text{Cl} + \text{HCl} \]
This product is chloromethane (methyl chloride).
Butene and Hydrogen: The last reaction appears to refer to butene (CH2=CH-CH2-CH3) reacting with hydrogen gas (H2) in the presence of a catalyst (commonly nickel, platinum, or palladium). This is a hydrogenation reaction:
\[ \text{CH}_2=\text{CH-CH}_2\text{CH}_3 + \text{H}_2 \xrightarrow{H_{cat}} \text{CH}_3\text{CH}_2\text{CH}_2\text{CH}_3 \]
The product of this reaction is butane.
