DRAW LEWIS, KEKULE AND SKELETAL STRUCTURE OF:

(CH3)2NCH2CH3

We can't draw structures on this board an I tried but didn't locate one on the web.

To draw the Lewis, Kekule, and skeletal structures of (CH3)2NCH2CH3, follow these steps:

1. Begin by identifying the atoms in the molecule. In this case, we have carbon (C), nitrogen (N), and hydrogen (H).

2. Next, determine the total number of valence electrons for the molecule. Carbon contributes 4 valence electrons, nitrogen contributes 5, and hydrogen contributes 1 each. Since we have two methyl groups (CH3) and an ethyl group (CH2CH3), we need to consider the additional hydrogens. The methyl groups contribute 3 electrons each (1 from carbon and 2 from hydrogen), and the ethyl group contributes 5 (2 from each carbon and 1 from nitrogen). Adding them up, we have:

2 (C) + 1 (N) + 9 (H) = 12 + 5 + 9 = 26 valence electrons.

3. Now, let's start with the Lewis structure. Since carbon is generally the central atom, we place it in the center and connect it to the nitrogen atom with a single bond. Distribute the remaining electrons around the atoms, making sure to give each hydrogen atom a total of 2 electrons and each carbon atom a total of 4 electrons (except for the central carbon, which can have 6). The structure would look like this:

H
|
H — C — N — C — H
| |
H H

4. Next, let's draw the Kekule structure. In Kekule structures, we use lines to represent the bonds between atoms. Each bond represents two electrons. The Kekule structure of the molecule would look like this:

H H
| |
H-C=N-C-C-H
| | | |
H H H H

5. Finally, let's draw the skeletal structure. In skeletal structures, we simplify the molecule further by just showing the carbon and nitrogen atoms connected by bonds. The hydrogen atoms are generally omitted. The skeletal structure of the molecule would look like this:

CH3
|
CH2-N-CH2CH3

Note that in each structure, the carbon atoms are connected by single bonds, and the nitrogen atom is bonded to two hydrogen atoms and one carbon atom. The methyl groups (CH3) and the ethyl group (CH2CH3) are represented as branches connected to the central carbon atom.

Remember to always consider the valence electrons, connectivity, and bonding rules when drawing these structures.
