What is ch3-ch2-ch2-ch2-ch2-ch2-ch2-ch2-ch2-ch2-ch2-ch2-ch2-ch2-ch2-cooh?

Answer 1

Its called octanoic acid.

There are 8 carbons in the longest chain, therefore it begins with oct.

All of the carbon to carbon bonds are single (alkane). Therefore the middle is an.

And finally, the subgroup on the end is a carboxylic acid, therefore we add oic acid.

Therefore CH3 (CH2)6 COOH is called octanoic acid.

Answer 2

This is the chemical formula for dodecanoic acid, also known as lauric acid. It is a saturated fatty acid commonly found in coconut oil and palm kernel oil.
