Draw the structures of all isomeric alcohols of molecular formula C5H12O and give their IUPAC names.


The structures of all isomeric alcohols of C5H12O are given below:

(a)


Naming is done by the conventional method. The -OH group is attached on the first carbon.


(b)


3-Methylbutan-1-ol


Butane is the longest chain and methyl is the substituent group.


(c)


3-Methylbutan-1-ol


Longest chain is butane and conventional naming method is used.


(d)


2,2-Dimethylpropan-1-ol


Isomer is made by transforming the principal carbon into tertiary type. The longest chain is butane and named accordingly.


(e)


Pentan-2-ol


Longest chain is pentane and the numbering is chosen from the minimum position.


(f)


3-Methylbutan-2-ol


Butane is the longest chain, further numbering is done by choosing a minimum position for the -OH group followed by other substituents.


(g)


Pentan-3-ol


Conventional method of naming is used.


(h)


2-Methylbutan-2-ol


Butane is the longest chain and substituents are named accordingly by looking into minimum position.
