Current Question (ID: 17614)

Question:

$\text{The final product in the above sequence of reactions is-}$

Options:

1. $\text{CH}_3\text{COOH}$
2. $\text{CH}_3\text{CH}_2\text{COOH}$
3. $\text{CH}_3\text{CH}_2\text{CH}_2\text{OH}$
4. $\text{HOOC-CH}_2\text{CH}_2\text{CH}_3$

Solution:

$\text{Hint: The fourth reaction is an example of a nucleophilic addition reaction.}$ $\text{In the first reaction, benzene reacts with an acyl chloride in the presence of AlCl}_3 \text{ then a ketone is obtained as a product.}$ $\text{In the second reaction, reduction of ketone takes place and alkylbenzene is obtained as a product.}$ $\text{In the third step, Friedel craft acylation occurs at the para position. In the fourth reaction, cyanohydrin is obtained as a product.}$ $\text{In the final step, hydrolysis of the CN group takes place and the CN group is converted into the COOH group and reduction of the OH group also takes place.}$ $\text{The overall reaction is as follows:}$ $\text{(CH}_3)_2\text{CH-C-Cl} \xrightarrow{\text{AlCl}_3} \text{(CH}_3)_2\text{CH-C=O} \xrightarrow{\text{Clemmensen reduction}} \text{(CH}_3)_2\text{CH-CH}_2\text{Cl} \xrightarrow{\text{AlCl}_3} \text{CH}_3\text{CH}_2\text{CH}_2\text{OH}$
