What is Zeisel method?

Decribe dichromate test for alcohols?

Describe Ritter test for alcohols?

describe chromic acid test for alcohols?

Victor Meyer test is not given by

Compound $\left(A\right)$ gives positive Lucas test in $5$ minutes when $6.0 gm$ of $\left(A\right)$ is treated with $Na$ metal, $1120 ml$ of $H_2$ is evolved at $STP$. Assuming $\left(A\right)$ to contain one of oxygen per molecule, write structural formula of $\left(A\right)$. Compound $\left(A\right)$ when treated with $PB{r}_3$ gives $\left(B\right)$ which when treated with benzene in prsence of anhydrous $AlC{l}_3$ gives $\left(C\right)$. What are $\left(B\right)$ and $\left(C\right)$?

Which of the following statements is correct?

Which of the following pairs can be distinguished by using Lucas Test ?

Predict the correct statement with respect to $\mathrm{P}$ and $\mathrm{Q}$.

In the following reaction sequence, the alcohol is a

$\mathrm{R}-\mathrm{OH}\stackrel{\mathrm{ }\mathrm{P}+{\mathrm{I}}_{2 }}{\to }\mathrm{R}-\mathrm{I}\stackrel{ \mathrm{ }{\mathrm{AgNO}}_{2 }\mathrm{ }}{\to }{\mathrm{RNO}}_2\stackrel{ {\mathrm{HNO}}_{2 }\mathrm{ }}{\to }\mathrm{No} \mathrm{reaction}$

The structure of the compound that gives a tribromo derivative on treatment with bromine water is

Iso-butyl alcohol $\stackrel{\text{P}/{\text{I}}_2}{\to }\stackrel{{\text{AgNO}}_2}{\to }\stackrel{{\text{HNO}}_2}{\to }\stackrel{\text{NaOH}}{\to }\text{A}$

True statement about $\mathrm{A}$ is

Four hydroxy compounds have functional groups as shown.

$\left(\mathrm{A}\right)-{\mathrm{CH}}_2\mathrm{OH} \left(\mathrm{B}\right)-\underset{|}{\mathrm{C}}\mathrm{HOH} \left(\mathrm{C}\right)\mathrm{PhOH}\mathrm{ }\left(\mathrm{D}\right)\mathrm{Ph}-\underset{|}{\mathrm{C}}\mathrm{HOH}$

The purple colour $\mathrm{F}\mathrm{e}\mathrm{C}{\mathrm{l}}_3$ will be given by

Note: $\left(\mathrm{B}\right)$, $\left(\mathrm{C}\right)$ and $\left(\mathrm{D}\right)$ has modified.

In the following reaction sequence

$\mathrm{R}-\mathrm{OH}\stackrel{ \mathrm{ }\mathrm{P}+{\mathrm{I}}_{2 }\mathrm{ }}{\to }\mathrm{R}-\mathrm{I}\stackrel{ \mathrm{ }{\mathrm{AgNO}}_{2 }\mathrm{ }}{\to }{\mathrm{RNO}}_2\stackrel{ {\mathrm{HNO}}_{2 }\mathrm{ }}{\to }$ no reaction The alcohol is a

Which is correctly matched ?
 

To distinguish between salicylic acid and phenol one can use

Primary, secondary and tertiary alcohols can be distinguished by performing

Which of the following, on reactions with nitrous acid, followed by treatment with $\mathrm{NaOH}$, produces a blood-red colouration?

Phenol can be tested by
