Write the names of the next homologues of $CH_{3}CH_{2}OH$ and $HCOOH$.

(N/A) homologous series is a group of organic compounds having the same functional group and similar chemical properties,where each successive member differs by a $CH_{2}$ unit.
$1$. For $CH_{3}CH_{2}OH$ (Ethanol),the next homologue is obtained by adding a $CH_{2}$ group,which results in $CH_{3}CH_{2}CH_{2}OH$ (Propan$-1-$ol).
$2$. For $HCOOH$ (Methanoic acid),the next homologue is obtained by adding a $CH_{2}$ group,which results in $CH_{3}COOH$ (Ethanoic acid).
Therefore,the next homologues are Propanol and Ethanoic acid respectively.
