Three $CH_3$ are connected to the Carbon. This Carbon is then connected to an oxygen, which is connected to a hydrogen.
Work Step by Step
The condensed formula is $(CH_3)_3COH$. The subscript 3 indicates that there are three $CH_3$. Since the $CH_3$ are written besides the carbon,they are single bonded to the carbon. This carbon is single bonded to an oxygen, which is bonded to a hydrogen. With this arrangement, all the carbons have 4 bonds, oxygen has 2 bonds and two pairs of electrons, and the hydrogens have single bonds.
