When phenyl magnesium bromide reacts with $t-$butanol,the product would be

Explain why ethers and alcohols of comparable molecular mass have different boiling points.

In the reaction $R-OH + HX \to RX + H_2O$,what is the order of reactivity of alcohols?

$CH_2=CH-CH(OH)-CH_2-CH_2OH \xrightarrow{MnO_2} A$. $A$ is:

The conversion of $2-$methylpropan$-1-$ol to $2-$methylpropan$-2-$ol is:

Assertion : The ease of dehydration of the following alcohols is as shown in the image.
Reason : Alcohols leading to conjugated alkenes are dehydrated to a greater extent.
