Ethyl benzoate can be prepared from benzoic acid by using:
1. Propyl alcohol
2. Ethyl alcohol and dry HCl
3. Ethyl chloride
4. Sodium ethoxide
Product 'P' in the above reaction is:
1. | 2. | ||
3. | 4. |
\(CH_3CHO+HCN\rightarrow CH_3CH(OH)CN\\ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\downarrow{\bf{H.OH}}\\ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~CH_3CH(OH)COOH~\)
1. 100 % R-isomer
2. 100% S-isomer
3. 50% R + 50% S-isomer
4. 20% R + 80% S-isomer
In a set of reactions acetic acid yielded a product D
\(\begin{aligned} &CH_3COOH \xrightarrow{SOCl_2} A \xrightarrow[\text{Anhy.}\ AlCl_3]{\text{Benzene}} B\\& B \xrightarrow{HCN}C\xrightarrow{H_2O}D \end{aligned}\)
The structure of D would be:
1. | 2. | ||
3. | 4. |
