Draw the structures of all isomeric alcohols of molecular formula C5H12O and give their IUPAC names. (ii)Classify the isomers of alcohols in question 11.3(i)as primary, secondary and tertiary alcohols.
(i)The structures of all isomeric alcohols of molecular formula,C5H12O are shown below:
(ii)Primary alcohol:Pentan-1-ol;2-Methylbutan-1-ol;
3-Methylbutan-1-ol;2,2-Dimethylpropan-1-ol
Secondary alcohol:Pentan-2-ol;3-Methylbutan-2-ol;
Pentan-3-ol
Tertiary alcohol:2-methylbutan-2-ol

Arrange the following compounds in increasing order of their boiling points:

The reaction 
suggests that phenol is :
In the reaction R–OH + HCl $\xrightarrow{\text{ZnCl}_2}$ RCl + H$_2$O, what is the correct order of reactivity of alcohols?

A ladder of fixed length \( h \) is to be placed along the wall such that it is free to move along the height of the wall.
Based upon the above information, answer the following questions:
(iii) (b) If the foot of the ladder, whose length is 5 m, is being pulled towards the wall such that the rate of decrease of distance \( y \) is \( 2 \, \text{m/s} \), then at what rate is the height on the wall \( x \) increasing when the foot of the ladder is 3 m away from the wall?
