What makes functional programming languages declarative as opposed to Imperative?

On many articles, describing the benefits of functional programming, I have seen functional programming languages, such as Haskell, ML, Scala or Clojure, referred to as “declarative languages” distinct from imperative languages such as C/C++/C#/Java. My question is what makes functional programming languages declarative as opposed to imperative.

What is the difference in the implementation of a monad in a purely functional language with respect in an imperative language?

For a long time, the use of these Monad structures has been restricted to a very small circle of languages, many of them purely functional (mainly due to problems related to the management of the IO).
Recently, these structures have also been adapted to imperative languages

My question is: we talk about same design pattern, Monad, but what is the difference in the implementation of a monad in a purely functional language with respect to the same design pattern but implemented into of the imperative programming ?

What change? Sure not change the idea, but if we talk about of same design pattern implementation but into 2 different programming paradigm something must be different, probably the same information will come back, but we are using identical idea but in 2 different paradigms contexts so the side effect cannot be the same otherwise it would not have occurred to us to implement the monad for imperative language
