Question

Give balanced equations for the following reactions: 

(1) Benzaldehyde reacts with hydrazine.

(2) Acetic acid reacts with phosphorous pentachloride.

(3) Acetone reacts with sodium bisulphite.

Answer 1

 (1)   

 

(2) \[\ce{PCI5 + CH3COOH-> CH3COCI + HCI +POCL3}\]

(3) \[\begin{array}{cc}
\ce{CH3\phantom{................} CH3\phantom{..} OH}\\
\phantom{}\backslash \phantom{....................}\backslash \phantom{..}/\\
\ce{C=O + NaHSO3<=>C}\\
\phantom{.}/\phantom{....................}/\phantom{..}|\phantom{...}\\
\phantom{.....}\ce{H3C}\phantom{................}\ce{H3C}\phantom{...}\ce{SO- 3Na+}
\end{array}\]
