yes, but usually you would know because the 11/12 speed chains are more expensive. for 5 speed it should be cheapest chain available.

Sidenote, worn and new chains/ chainrings dont mix well either

Going to guess you told them it was an old 10 sp. They took it to mean 1 or 2×10 which is now 10sp when you meant 1 or 2×5, as in a really old 10sp. You need a 7/8/9sp chain or even just a 3/32. Chains get a lot narrower after 9sp.

Whoa, did you tell them you had an antique Italian bike with cottered cranks?
Modern, as in the last 40 years modern, multi speed chains ALL share the same length between bushings. A 7 speed chain and an 11 speed chain are only different in width.
What you have is NOT that.

So it looks like you’ve got a wear burr every second tooth and the chain is hanging up on them. Kinda like modern narrow-wide chainring teeth! I bet if you moved the chain forward one link it would mesh slightly better. You could file/grind off the burrs but I bet you’d have problems with chainsuck – this is when the chain doesn’t disengage from a sprocket and gets stuck as the chain wraps over it…. Do you still have the old chain?

You would probably be best getting a single speed chain, even though your bike has gears modern multispeed chains are all going to be too narrow.

Is the chainring so worn that a new chain won’t fit on? How old was the chain that came off?

Wow I love this. This is like the Antikythera Mechanism of bike problems.

Why everyone is missing the point here, it cleary doesn’t fit LENGTHWISE. I believe you should look in Italian bicycle specific forums and probably lurk for new old stock parts.

I cant read the chain too well, but it looks like it says ‘Z 8.3’ if thats true, you’re trying to use an 8 speed chain on what im assuming is an old 10 speed (2×5). You need a chain that actually fits 5 speed drivetrains, like for reference Sunlite SCN-MS chains, https://www.ebay.com/itm/282510776424
Or for an alternative you can also get their SCN-MSi chains. There are alternatives as well, like KMC’s 6 speed chains, but they potentially might not fit
