What does it exactly mean when you have to name the compound in alphabetical order? Thanks !!

I'm assuming you're talking about naming coordination compounds? If so, when naming the ligands you usually name them in alphabetical order:
Ex: [Cr(Cl)2(NH3)4]+
Ligands: Chlorine, Ammonia
Naming: tetraammine-dichloridochromium(III) ion

The name of the compound is just written out with the substituents in alphabetical order followed by the base name.
Here are some examples:
1) 4-ethyl-2-methylhexane
(the e in ethyl comes before the m in methyl)
2) 2,3,5-trimethyl-4-propylheptane
(don't look at the number prefixes when naming. You look at the m in methyl and then the p in propyl)
