Dear Student

 

It is very simple.

Pentane-1-ol

 

First look properly at the name. Pentane is a five chain alkane. So draw a fiv chain alkane.

 

CH₃CH₂CH₂CH₂CH₃

 

Now the other part which says  1-ol.

-ol is a suffix used for alcohol functional group. so there is an OH group at the five membered chain. The position of the OH group is 1. So now redraw the structure keeping in mind the valency of carbon.

 

CH₃CH₂CH₂CH₂CH₂OH

 

We hope that clarifies your query.
