The reaction ${C_2H_5Cl} \xrightarrow{[H]} x$ produces $x$ as:

$CH_4 + Cl_2 \xrightarrow{hv} CH_3Cl + HCl$
To obtain high yields of $CH_3Cl$,the ratio of $CH_4$ to $Cl_2$ must be

$Ph^{-}MgBr + CH_3-CH(OH)-CH_3 \to A$. What is the product $A$?

What are $X$,$Y$ and $Z$ in the following reactions?

What is the difference in molar masses of Undecane and Decane?

Give the conversion reaction for $methane$ to $ethane$.
