Explanation:
Molecular formula of the compound =
The carbon chain in the molecule will look like :
1. [tex]H_2C=CH-CH_2-CH_2-CH_2-OH[/tex]
2. [tex]H_3C-CH=CH-CH_2-CH_2-OH[/tex]
3. [tex]H_3C-CH-CH=CH-CH_2-OH[/tex]
4. [tex]H_3C-CH_2-CH_2-CH=CH-OH[/tex]
No branching is present, so that means the valency of the carbon will be fulfilled by 10 hydrogen atoms and 1 oxygen atom
