F

The first three members of a family of organic compounds are:

CH3OH\mathrm{CH_{3}OH}CH3​OH, C2H5OH\mathrm{C_{2}H_{5}OH}C2​H5​OH and C3H7OH\mathrm{C_{3}H_{7}OH}C3​H7​OH

Another member of the same family has a relative formula mass of 88.0.

Relative atomic mass (ArA_{r}Ar​): C = 12.0, H = 1.0, O = 16.0

What is the formula of this member?
