1. All of the following are structural isomers of CH2=CHCH2CH=CHCH3 EXCEPT
Is it D?
2. Almost all of the amoino acids found in living organisms are in the L-form. L-Alanine and D-alanine are

Thanks for helping out!

Isn't b just written the reverse of the original molecule? That makes it the same compound, not a different isomer.I think optical isomers is correct.
