Draw the skeletal structure for (CH3)3CCH2COOCH3
We can't draw structures on the board. What you have is an ester.
Here is the way an ester looks where the first R is the (CH3)3CCH2 and the R' is the CH3 on the right.

To draw the skeletal structure for (CH3)3CCH2COOCH3, you need to consider the functional groups and the connectivity of the atoms.
1. Start by identifying the central carbon atom (C) in the structure. In this case, it is the carbon atom attached to three methyl groups (CH3).
2. Next, identify the atoms directly attached to the central carbon atom. In this case, there is a hydrogen atom (H) and another carbon atom (C).
3. For the carbon atom (C) attached to the central carbon atom, identify the atoms directly attached to it. In this case, there is a hydrogen atom (H) and a functional group, which is the acyl group (C=O) attached to another oxygen atom (O).
4. Connect all the identified atoms with single bonds (lines) according to the given connectivity.
Here is the skeletal structure for (CH3)3CCH2COOCH3:

Note: Methyl groups (CH3) are represented as single hydrogen atoms attached to a carbon atom.
To draw the skeletal structure for (CH3)3CCH2COOCH3, follow these steps:
1. Start with the central carbon atom. It is surrounded by three methyl groups (CH3), and hence represented as (CH3)3C. Place this carbon atom in the center.

2. Next, add a carbon atom bonded to the central carbon atom. This carbon atom is connected via a single bond and has two hydrogen atoms (CH2) attached to it.

3. Attach an oxygen atom to the second carbon atom via a double bond (C=O).

4. Finally, add a methyl group (CH3) to the oxygen atom. This methyl group is connected via a single bond.
