@Oh_Gee, yes, you are correct, this is the logic behind. If the IR was done on salt of caroxylate, you would be observing an IR at around 1600 for the carbonyl, and the OH group would not be observed since carboxylate does not have the OH group since it is deprotonated. For your info, my dog is a japanese breed, shiba inu. It is not that expensive, you usually can get one for around 1200. He's extremely intelligent and capable of logical reasoning. Once I bought pack of beef jerky and placed it on the shelf atop of a desk. However, he pushed a chair to the desk, then jumped onto the chair and then onto the desk, and my beef jerky was gone after I came back home. Another time, he was behaving so bad and chewing my mattress, so I scolded at him... At first, he stayed away from me. An hour later, he ripped my pillow open and pooped in the middle, these behavior are all due to the fact that he is extremely spoiled by me and my brother. However, this dog is extremely loyal, and can save you from danger. Just about a month ago, there was a fire in one of the apertment in my building. I did not notice that because I turned on the AC with my bedroom door closed, so I did not smell the smoke. He smelt it, and kept barking at me. I then opened my bedroom door, there was a lot of smoke flowing from outside. I grabbed him immediately and ran downstairs.
