Chemistry for Today: General, Organic, and Biochemistry
- The arrangement of atoms in several biologically important molecules is given here. Complete the Lewis structures of these molecules by adding multiple bonds and lone pairs. Do not add any more atoms. (a) the amino acid serine: (b) urea: (c) pyruvic acid: (d) uracil: (e) carbonic acid:arrow_forwardIs violet light (with a wavelength of 400 nm) sufficiently energetic to break a carbon-carbon single bond (the average C-C bond energy is 346 kJ/mol)?arrow_forwardWhich statements are true about resonance contributing structures? (a) All contributing structures must have the same number of valence electrons. (b) All contributing structures must have the same arrangement of atoms. (c) All atoms in a contributing structure must have complete valence shells. (d) All bond angles in sets of contributing structures must be the same.arrow_forward
- Following is a structural formula of benzene, C6H6, which we study in Chapter 21. (a) Using VSEPR, predict each HCC and CCC bond angle in benzene. (b) State the hybridization of each carbon in benzene. (c) Predict the shape of a benzene molecule. (d) Draw important resonance contributing structures.arrow_forwardAcrylamide, 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_forwardUsing the values of electronegativity given in Table 1.5, predict which indicated bond in each set is more polar, and using the symbols + and , show the direction of its polarity. (a) CH3OH or CH3OH (b) CH3NH2 or CH3 PH2 (c) CH3 SH or CH3SH (d) CH3F or HFarrow_forward
- Molecules in space: (a) In addition to molecules such as CO, HCl, H2O, and NH3, glycolaldehyde has been detected in outer space. Is the molecule polar? (b) Where do the positive and negative charges lie in the molecule? (c) One molecule found in the 1995 Hale-Bopp comet is HC3N. Suggest a structure for this molecule.arrow_forwardDraw out the organic shorthand for the molecules below, and then draw another possible resonance structure of the same molecule next to with arrows to show electron movement. -CH3CH2CONH3 -CH3CH2COOHarrow_forwardHow many π electrons are present in the molecule below? a) 2 b) 4 c) 6 d) 8arrow_forward
- Which statements are true about resonance contributing structures? (a) All contributing structures must have the same number of valence electrons. (b) All contributing structures must have the same arrangement of atoms. (c) All atoms in a contributing structure must have complete valence shells. (d) All bond angles in sets of contributing structures must be the same.arrow_forwardWhich has the shorter N - O length, NO2- or NO3-?arrow_forwardThese structures contain at least one error. Identify the errors and suggest a correct structure. All structures should be neutral (uncharged) and formal charge for each atom should be 0.arrow_forward
