Answer
Aldehydes that have the formula $C_{5}H_{10}O$:
pentanal, 2-methylbutanal, 3-methylbutanal & 2,2-dimethylpropanal.
Ketones that have the formula $C_{5}H_{10}O$:
pentanone, 3-methyl-2-pentanone & 3-pentanone.
Work Step by Step
Aldehydes that have the formula $C_{5}H_{10}O$ are:
pentanal, 2-methylbutanal, 3-methylbutanal & 2,2-dimethylpropanal.
Ketones that have the formula $C_{5}H_{10}O$ are:
pentanone, 3-methyl-2-pentanone & 3-pentanone.
To draw the structure of aldehyde, draw 5 C in straight chain and C1 carbon will be the aldehyde C. We get pentanal.
Draw 4 C in straight chain and C1 carbon will be the aldehyde C. place one methyl group at C2 position to get 2-methyl-1-butanal.
Draw 4 C in straight chain and C1 carbon will be the aldehyde C. place one methyl group at C3 position to get 3-methyl-1-butanal.
Draw 4 C in straight chain and C1 carbon will be the aldehyde C. place two methyl groups at C2 position to get 2,2-dimethyl-1-propanal.
Draw 5 C in straight chain and the C2 carbon will be the ketone 'C'. we get pentanone.
Draw 4 C in straight chain and the C2 carbon will be the ketone 'C'. now place one methyl group at C3 position to get 3-methyl-2-butanone.
Draw 5 C in straight chain and now C3 carbon will be the ketone 'C'. we get 3-pentanone.
