Vedclass · Answer

(D) The preparation of looking mirrors (silvering of glass) is based on the Tollens' test,which involves the reduction of ammoniacal silver nitrate ($AgNO_3$ + $NH_4OH$) to metallic silver by an aldehyde. $HCHO$ (formaldehyde) is commonly used as the reducing agent to deposit a thin,uniform layer of silver on the glass surface. Therefore,the process involves the use of ammoniacal silver nitrate and $HCHO$.

What is the correct order of reactivity of the following compounds towards a Grignard reagent?
$(I)$ $CH_3CHO$
$(II)$ $HCHO$
$(III)$ $CH_3COC_6H_5$

Compound $x$ having molecular formula $C_3H_6O$ is reduced by Red $P/HI$ to give compound $y$ $(C_3H_8)$. Since $x$ reduces Tollen's reagent,what is the possible structure of $x$?

The following reagent converts $C_6H_5COCHO$ to $C_6H_5CHOHCOONa$.
