It is a forum rule (see red link above) that you must show your attempt before we can help you.

Hello Dansey: I'd like to welcome you here to the Chemical Forums.  But I'd like to ask you to trouble yourself to read our Forum Rules{click}.  You agreed to these rules as a condition of signing up for our forum, and they apply to you, whether you agree with them or not, or even if you're unaware of them.  And you'll see that you've violated a number of them, repeatedly.

You've posted two pictures, one without then one with answers.  But you need mechanisms.  Try this -- show us just one, and try to draw the mechanism.  Let us see what you can do, and lets try to work out what you can't do.

Do you need mechanisms? Or are you just asking if your products are correct?
