Answer 1

Each Part: 0.5 Mark

i) \underset{Ethane}{C_2H_6}\xrightarrow[SiO_2 - Al_2O_3]{500^\circ C} \underset{Ethylene}{C_2H_4}+ H_2\)

ii) $\underset{Methyliodide}{C{H}_{3}I}+HI\underset{{150}^{\circ }C}{\overset{RedP}{\to }}C{H}_4+I_2$

iii) $\underset{Methane}{2C{H}_4}+O_2\underset{{200}^{\circ }C}{\overset{Cutube}{\to }}\underset{Methylalcohol}{2C{H}_3-OH}$

iv) $\underset{Methane}{C{H}_4}+C{l}_2\stackrel{Diffusedsunlight}{\to }\underset{Methylchloride}{C{H}_{3}Cl}+HCl$

v) $\underset{Methane}{C{H}_4}+4C{l}_2\underset{sunlight}{\overset{Diffused}{\to }}\underset{Carbontetrachloride}{CC{l}_4}+4HCl$

vi) $\underset{Sodiumacetate}{C{H}_{3}COONa}+NaOH\underset{Heat}{\overset{CaO}{\to }}C{H}_4+N{a}_{2}C{O}_3$

vii) $\underset{Acetaldehyde}{C{H}_{3}CHO}+4\left[H\right]\underset{Conc.HCl}{\overset{Zn-Hg}{\to }}\underset{Ethane}{C{H}_3-C{H}_3}+H_{2}O$

viii) $\underset{Ethane}{C_2{H}_6}+O_2\underset{350-{500}^{\circ }C}{\overset{MoO}{\to }}\underset{Acetaldehyde}{C{H}_{3}CHO}+H_{2}O$

ix) $\underset{Ethane}{C_2{H}_6}+O_2\underset{350-{500}^{\circ }C}{\overset{MoO}{\to }}\underset{Acetaldehyde}{C{H}_{3}CHO}+H_{2}O$

$C{H}_{3}CHO\underset{K_{2}C{r}_2{O}_7+Dil.H_{2}S{O}_4}{\overset{\left[O\right]}{\to }}\underset{Aceticacid}{C{H}_{3}COOH}$

x) $\underset{Methane}{C{H}_4}\underset{sunlight}{\overset{Diffused}{\to }}\underset{Chloroform}{CHC{l}_3}+3HCl$
