Why did Obito left hand got melted and detached.. wasn't his right hand made
of zetsu.. his left hand was not crushed under the rock.

This is from episode 248.

Well, the way that you're looking at it Obito's right arm was squished, but
the truth is that his left arm is squished, it's just the way you're looking
at it. :)
