Question

Alkanes, alkenes, alkynes, alcohol, phenol, ether, ester, aldehyde, ketone, acid pls arrange in the sequence of increasing oxidation number. ( If one compound were to be transformed into the other

Answer 1

If you start with an alkane with a CH3 group,

The alkane can be oxidized to a primary alcohol.The alcohol can be oxidized to an aldehyde The aldehyde can be oxidized to a carboxylic acid.
Alkanes -->1° alcohols -->
aldehydes --> acids

If you start with an alkane with a secondary carbon:

​​​​​​The secondary carbon can be oxidized to a secondary alcohol. The secondary alcohol can be oxidized to a ketone. The ketone can even be oxidized to an ester.
Alkynes --> 2° alcohols -->
ketones --> esters

Oxidation involving multiple bonds :

Alkanes can be oxidized to alkenes. Alkenes can be oxidized to alkynes.
Alkanes --> alkenes --> alkynes
