Question

Complete the following reactions:

(i) $C_{2}H_{5}I + H_{2}\underset{C_{2}H_{5}OH}{\overset{\quad Zn - Cu\quad}{\rightarrow}}x$

(ii) $CH_{3}COONa + H_{2}O\overset{\quad Electrolysis\quad}{\rightarrow}Y$

(iii) $CH_{3}CH_{2}CH_{2}CH_{2}CH_{2}CH_{3}\overset{\quad Cr_{2}O_{3}/Al_{2}O_{3}\quad}{\rightarrow}Z$

• A. $x = C_{2}H_{6},Y = C_{2}H_{6},Z = C_{6}H_{6}$
• B. $x = CH_{4},Y = CH_{3}COOH,Z = CH_{3}CH_{3}$
• C. $x = C_{2}H_{6},Y = CH_{4},Z = C_{4}H_{10}$
• D. $x = C_{2}H_{6},Y = CH_{4},Z = C_{5}H_{10}$

Answer 1

Answer: (A)

$x = C_{2}H_{6},Y = C_{2}H_{6},Z = C_{6}H_{6}$

Answer 2

: (i) $C_{2}H_{5}l + H_{2}\underset{C_{2}H_{5}OH}{\overset{\quad Zn - Cu\quad}{\rightarrow}}\underset{(X)}{C_{2}H_{6}} + HI$

(ii) $CH_{3}COONa + H_{2}O\overset{\quad Electrolysis\quad}{\rightarrow}\underset{(atanode)}{CH_{3}CH_{3}} + \underset{(atcathode)}{H_{2}}$

(iii) $\mathrm { CH } _ { 3 } \mathrm { CH } _ { 2 } \mathrm { CH } _ { 2 } \mathrm { CH } _ { 2 } \mathrm { CH } _ { 2 } \mathrm { CH } _ { 3 }$ $\overset{\quad CR/o_{3}/aL_{2}o_{3}\quad}{\rightarrow}$
