Can someone please look over my answers to be sure that I am on the right track this homework is about defining reasons for a physical property increase between two chemical compounds, the 6th question wants a structure that have a similar density to that of H20.
1.-5. Match each pair of compounds on the left a its corresponding melting points (m.p.) or boiling points (b.p.) in oCto a major reason, given on the right, why the physical property increases. Answers may be repeated. Remember that "di" means two. NH20CH2)sNH2 is commonly known as cadaverine. 1. pentane-1,5-diol (m.p. -18), NH2(CH sNH2 (m.p. 12) -l a. easier to rotate in place 2. pentane-1,5-diol (m.p. -18), 2,2-dimethylpropane-1.3.diol (m.p. 129) E b. greater weight c. more hydrogen bonds 4. 2,2-dimethylpropane-1,3-diol (b.p. 208), pentane-1,5-diol (b.p. 242) A d. more polar bonds e, more van der Waal interactions 5. NH2(CH2)5NH2 (b.p. 179), butane-1,4-diol (b.p. 235) 6. Using the method that we learned in class to estimate specific gravities and given the following atomic weights (C 12, H- 1, N-14, o 16) which compound has a density closest to that of water?
