# Chapter 1 - Introduction and Review - Problems: Problem 1-9 e

3 $CH_3$ are connected to the C, which is connected to a carbon connected to an O. This C is connected to a CH which is double bonded to another $CH_2$.

#### Work Step by Step

The condensed formula is $(CH_3)_3CCOCHCH_2$. Since $(CH_3)_3$ has three as a subscript there are three $CH_3$ connected to the next carbon. This carbon is double bonded to an Oxygen with two lone pairs and bonded to the next CH. This CH is double bonded to next $CH_2$. The oxygen has two lone pairs.
