Chemistry - ALCOHOL & ETHER Question with Solution | TestHub

Lucas test will be given by all the given alcohols within 5 minutes as all are $2^{\circ }$ alcohols. Exact structure can be known by molecular mass or formula of alcohol which will be obtained as follows : Let molecular mass of alcohol be $M$. $\frac{56}{22400}=\frac{0.22}{M}$ or, $M=\frac{22400\times 0.22}{56}=88$ The general formula of alcohols is ${\mathrm{C}}_n{\mathrm{H}}_{2n+1}\mathrm{OH}$. The molecular mass 88 corresponds to the value of $n=5$. Thus, the $2^{\circ }$ alcohol is ${\left({\mathrm{CH}}_3\right)}_2{\mathrm{CHCHOHCH}}_3$.
