Reactivity Of Alkanes
Question#1
Under suitable conditions alkanes cann't undergo ________ reactions. ? MDCAT2023
Substitution: \( CH_4 + Cl_2 \rightarrow CH_3Cl + HCl \)
Combustion: \( CH_4 + O_2 \rightarrow CO_2 + H_2O \)
Hydrogenation: Under sever conditions such as pressure and temperature along with metal catalysis, an alkane molecule can be hydrogenated. this necessitates however the breaking up molecules into smaller alkanes.
\( CH_3-CH_3 + H_2 \rightarrow 2CH_4 \)
Addition : Alkanes can't undergo addition reactions
