Carbon black,which is used in making printer's ink,is obtained by decomposition of

Which of the following conditions will give the maximum yield of $C_2H_5Cl$?

Which products are formed on the chlorination of $(CH_3)_3CH$? Also,provide a comparison of their composition.

Identify the product $C$ in the following reaction:
$CH_{3}CH_{2}COOH$ $\xrightarrow{NaOH} A$ $\xrightarrow{NaOH, CaO, \Delta} B$ $\xrightarrow{HNO_{3}, \Delta} C$

$A$ compound reacts with $Cl_2$ to give product $(B)$,and the reaction of product $(B)$ with $(Zn + \text{dilute } HCl)$ gives back the original substance $(A)$. Give the structures of $(A)$ and $(B)$.

Identify the final product $C$ in the following reaction sequence:
$Br-(CH_2)_5-Br$ $\xrightarrow{Na, \text{D.E.}} A$ $\xrightarrow{Br_2, \Delta} B$ $\xrightarrow{\text{alc. KOH}, \Delta} C$
