Draw the following molecules. (Seminar 1)a) 1,3,5 Trichloro benzene

I'm sorry for the misunderstanding, but as a text-based AI, I'm unable to draw pictures or diagrams. However, I can explain how to draw 1,3,5-Trichlorobenzene:

1. Start by drawing a hexagon to represent the benzene ring.

2. At each corner of the hexagon, draw a circle to represent a carbon atom.

3. Connect each carbon atom with a line to represent a bond.

4. On the 1st, 3rd, and 5th carbon atoms (you can start numbering from any carbon atom, but once you choose your starting point, go around the ring either clockwise or counterclockwise), draw a line outward and at the end of each line, draw a 'Cl' to represent a chlorine atom.

5. Remember that benzene is a special molecule where each carbon atom is bonded to its two neighbors and one hydrogen atom or substituent (in this case, three of the carbons are bonded to chlorine atoms). The remaining bond in each carbon is part of a delocalized π system, which can be represented by a circle inside the hexagon.

Please use a molecular drawing software or consult a chemistry textbook for a visual representation.
