Current Question (ID: 10887)

Question:

$\text{A total number of structural isomeric aldehydes and ketones that can exist with the molecular formula C}_5\text{H}_{10}\text{O are :}$

Options:

1. $5$
2. $8$
3. $6$
4. $7$ (Correct)

Solution:

$\text{Hint: Aldehyde contains -CHO group and ketone contains } \frac{\text{O}}{\|} \text{-C-}$ $\text{The chemical formula of ketone and aldehyde is the same. if we draw the structure of aldehyde, there are four possible isomers formed given below}$ $\text{Aldehydes:}$ $\text{1. Pentanal}$ $\text{2. 2-methyl-butanal}$ $\text{3. 3-methyl-butanal}$ $\text{4. 2,2-dimethylpropanal}$ $\text{If we draw the structure of Ketone there are 3 possible isomers formed given below,}$ $\text{Ketones:}$ $\text{1. 3-Pentanone}$ $\text{2. 2-pentanone}$ $\text{3. 3-methyl 2-pentanone}$ $\text{There are 4 aldehydes and 3 ketones exist with C}_5\text{H}_{10}\text{O. Hence, there are 7 structural isomers of C}_5\text{H}_{10}\text{O.}$
