  2. 1. Ur right
    2. its not D.. Its A
    3. i am not sure about this one.

    Hope That Helps! :)

  3. No, I still disagree with 2 and 3.
    2. When you say "both between and within organic and inorganic compounds" you are saying ALL inorganic compounds are covalent bonds and you know that isn't right. Also I have no idea what kind of ANY bond is formed between organic compounds. Perhaps a hydrogen bond here and there but certainly no covalent bonds.
    3. Hydrogen bonds are formed between H and an HIGHLY electronegative atom of a neighboring molecule. The C-H bonds is slightly (with an emphasis on slightly) polar since C has an EN (electronegativity) of 2.4 and H is 1 but that isn't enough for a H bond to form with a neighboring atom. The ONLY elements that have an EN high enough to form hydrogen bonds with H are O, N and F. No others.

  7. You guessed on the first one and you were wrong. You guessed on the second one and were wrong. Now you've guess on the third one and missed that one too. One of my chemistry teachers in undergraduate school always told us not to use the eenie, meenie, meiny, mo method. I guess that's what you did. Seriously, tell my why you don't (didn't) think B is the correct answer. If I write CH3CH2CH2CH2CH3 that backbone of n-pentane is comprised of so-called pure covalent bonds with the C-C linkage. Why did you not recognize that. Be honest. It helps me help other in the future.

  8. Sorry, I just didn't understand the question and didn't know what the "backbone" was suppose to be. I just knew that covalent bonds were found in carbon-based organic molecules.

  10. OK. Your explanation is a little hard to buy. Neither C nor D answers are about organic compounds. C talks about inorganic compound so you shouldn't have picked that. D is give-a-way no answer when it says ALL. I would have thought you would pick a or b first. Anyway, use this as a learning experience. I think chemistry is a lot of fun but when one falls one must get up and go on. We learn from our mistakes---and boy have I made a lot of chemistry mistakes in my life.
