Question

big idea/ learning goal demonstration

1. name the following molecules:

i can name organic compounds.

Explanation:

Step1: Identify the longest carbon - chain

For the first molecule, the longest carbon - chain has 6 carbon atoms (hexane). For the second molecule, the longest carbon - chain with the double bond has 4 carbon atoms (butene).

Step2: Locate and name substituents

In the first molecule, there is an ethyl group at the 3 - position and two methyl groups at the 2 and 4 positions. In the second molecule, since the two methyl groups are on opposite sides of the double bond, it is a trans isomer.

Answer:

a. 3 - ethyl - 2,4 - dimethylhexane
b. trans - but - 2 - ene
