Draw the HEXAGONAL skeletal (bond - line) structure of a hydrocarbon containing a substituted five-membered ring with one double bond ( cyclopentene) with the following molecular formula of C6H10. C-H bonds are implied show work

Show all the bonds in the drawing please  dont do ch3ch2ch draw it out ty

Hi! I found some answers for this question but I am not sure about it.Can you explain the question?

2. The full structural formulae of three organic compounds, P, Q and R, are shown below. H H H H HH HHHH Н-С -с- Н H-C- C - C = C – H H - C - C = C – C – H H H H H Q P (a) State one similarity between P, Q and R in terms of their molecular formulae. (b) Name the homologous series that compounds P, Q and R belong to. (c) State one similarity between Q and R in terms of chemical bonding id) Which of these compounds are isomers? Explain your answer.

Using a table of average bond enthalpies. Table 6.2 ( Sec. 6-6b), estimate the enthalpy change for the industrial synthesis of methanol by the catalyzed reaction of carbon monoxide with hydrogen.

Following are heats of combustion per mole for methane, propane, and 2,2,4-trimeth-ylpentane. Each is a major source of energy. On a gram-for-gram basis, which of these hydrocarbons is the best source of heat energy?

(Chemical Connections 11C) What are HFCs and HCFCs? How does their use in refrigeration systems prevent the environmental problems associated with the use of Freons?

The bond length of the indicated C-C single bond in hexa-1,3,5-triene is about 146 pm, which is considerably shorter than that in ethane, H3C-CH3. (a) How much shorter is it? Hint: See Figure 14-2, page 685. (b) Which occupied T MOS (obtained in Problem 14.32) help decrease this bond length? (c) If an electron were promoted from the HOMO to the LUMO, would the length of the C-C single bond increase, decrease, or stay roughly the same? Explain. 146 pm
