hi all,

I know that the first reaction is correct. my concern is pointed to the second reaction. is it correct??

The second one is wrong - you've added 2 extra carbons is the biggest problem, where do they come from? Based on the first reaction, what would be an expected product in the second one?

In your first example, the C-S bond was replaced with what kind of bond?  Use this reaction as your model.
