The IUPAC name of $CH X_{3} CH X_{2} - COO - CH X_{3}$ is:

Apropyl methanoate
Bmethyl propanoate
Cmethyl propanamide
Dethyl ethanoate

Answer: B

In an ester R-CO-O-R' the acyl part gives the alkanoate name and the group on oxygen is the alkyl word. The acyl part

CH X_{3} CH X_{2} CO X^{-}

has three carbons (propanoate) and the group on oxygen is methyl. The name is methyl propanoate.
