On page 29 of the Organic Chemistry Textbook, I noticed that when naming organic molecules like methylcyclohexadiene, it can be spelled out with an "a" or without an "a". Which one is right? or When are we supposed to used the A within the name? Meaning: methylcyclohexdiene or methylcyclohexAdiene

I'm pretty sure that wouldn't matter too too much. As long as you have the correct suffix/infix like -ene, -ane, yne, ect. you should be fine.

I was very confused by this as well. After searching up methylhexdiene on Google, the only results are for methyl (or dimethyl) hexadiene. There seems to be no methylhexdiene (without the "a"). Even when searching up "hexdiene", the only results are for "hexadiene". I would assume that it's supposed to be hexadiene. Hopefully someone can give a definitive answer regarding this topic.

It must have the "a" if it is a polyene.

It does matter, typically every mistake is -1 point.
