Write the structures of the following compounds.

(i) α-Methoxypropionaldehyde           

(ii) 3-Hydroxybutanal

(iii) 2-Hydroxycyclopentane carbaldehyde   

(iv) 4-Oxopentanal

(v) Di-sec. butyl ketone                                 

(vi) 4-Fluoroacetophenone 

<p><strong> (i)</strong> The compound contains ether group and an aldehydic functional group with the longest chain having 3 carbon atoms. α means the position of the carbon atom attached to attached to the carbon atom of the functional group, in this case, it is an aldehyde functional group.</p><p><strong> (ii)</strong> The compound contains an alcoholic group and an aldehydic functional group with the longest chain having 4 carbon The numbering of the chain starts from a carbon atom of aldehyde group.</p><p><strong> (iii)</strong> The compound contains an alcoholic group and an aldehydic functional group, with the longest chain having 5 carbon atoms, which are cyclic in The numbering of the chain starts from a carbon atom of the aldehyde group attached to the cyclopentane ring.</p><p><strong> (iv)</strong> The compound contains ketone group and an aldehydic functional group with the longest chain having 5 carbon The numbering of the chain starts from a carbon atom of aldehyde group.</p><p><strong> (v)</strong> The compound contains ketone functional group with the longest chain having 8 (butyl is used because there is two similar butyl group attached to the carbonyl carbon of ketone group) carbon</p><p><strong> (vi)</strong> The compound contains a fluorine atom and a ketone functional group with the longest chain which is a derivative of a phenyl group and an acetyl substituent.</p>
