- Acrylamide, H2C=CHCONH2, is a known neurotoxin and possible carcinogen. It was a shock to all consumers of potato chips and french fries a few years ago when it was found to occur in those products. (a) Sketch the molecular structure of acrylamide and identify all bond angles. (b) Indicate which carbon-carbon bond is the stronger of the two. (c) Is the molecule polar or nonpolar? (d) The amount of acrylamide found in potato chips is 1.7 mg/kg. If a serving of potato chips is 28 g, how many moles of acrylamide are you consuming?arrow_forwardDraw a valid Lewis structure for each ion: (a) OH −; (b) H 3O +.arrow_forwardCyanogen (CN)2 is known as pseodohalogen because it has some properties like halogens. It is composed of two CN’s joined together.(i) Draw the Lewis structure for all the possible combination for (CN)2.(ii) Calculate the formal charge and determine which one of the structures that you have drawn is most stable.(iii) For the stable structure, determine the geometry around the two central atoms.(iv) For the stable structure, draw the dipole arrows for the bonds.(v) Base on the stable structure, determine the polarity of molecule and state your reason.arrow_forward

- (b) The Murchison meteorite that landed in Australia in 1969 contained 92 different amino acids, including 21 found in Earth organism A skeleton structure (single bond only) of one of these extraterrestrial amino acids is shown below. Draw a Lewis structure, and identify any atoms having a nonzero formal charge. H3N. C ČH2 ČH3 (c) Draw the orbital diagrams and Lewis symbols to depict the formation of Na* and CI ions from the atoms. Give the formula of the compound formed. (d) The predicted bond length for HF is 109 pm (the sum of the covalent radii of H, 37 pm and F, 72 pm), however the actual bond length for HF is shorter (92 pm). It was observed that the difference between predicted and actual bond lengths becomes smaller going down the halogen group from HF to HI Describe these observationsarrow_forwardUse electronegativity values to classify each bond as nonpolar, polar covalent, or ionic: (a) Cl 2; (b) HCl; (c) NaCl.arrow_forwardb.
