| This question is about hexane, C6H14, and hex-1-ene, C6H12. What test would you use to distinguish between hexane and hex-1-ene Give the results of the test for each substance, | show 🗑
|
||||
| Give the results of the test for each substance, | show 🗑
|
||||
| Give the results of the test for each substance, | show 🗑
|
||||
| Explain why stereoisomerism can occur in alkenes, and why hex-2-ene has stereoisomers but hex-1-ene does not | show 🗑
|
||||
| Hex-1-ene has no group which takes priority on the C at one end of C=C &.. | show 🗑
|
||||
| The value for the enthalpy change of combustion in this experiment is different from the value given in data books. Suggest TWO reasons for this difference | show 🗑
|
||||
| A student suggested that the results would be more accurate if a thermometer which read to 0.1°C was used. Explain why this would not improve the accuracy of the result. A calculation is not required. | show 🗑
|
||||
| C6H12(l) + H2(g) → C6H14(l) (i) What catalyst is used in this reaction? | show 🗑
|
||||
| show | same(number and type of) bonds are broken.
and made in each reaction / one C=C (and one H-H) are broken and two C-H made
🗑
|
||||
| Chloroethae, C2H5Cl, can be made from either ethane or ethene.(i) What reagent and condition would be used to make chloroethane from ethane | show 🗑
|
||||
| State the type of reaction and mechanism by which this reaction occurs | show 🗑
|
||||
| What reagent would be used to make chloroethane from ethene | show 🗑
|
||||
| show | Higher atom economy from ethene /by Higher yield from ethane
🗑
|
||||
| From ethene | show 🗑
|
||||
| For ethene | show 🗑
|
||||
| show | Energy for man materials/lifetime of product/how often need replaced /metal rusts/plastic more easily punctured etc • ease of recycling/steel an excellent recyclable material/consequences of disposal/is it biodegradable? from a non-renewable resource?
🗑
|
||||
| show | C2H5 and the molecular formula C4H10.
🗑
|
||||
| show | 1.8 × 1024
🗑
|
||||
| The enthalpy change for the reaction CH4(g) ---> C(g) + 4H(g) is +1648 kJ mol–1. Hence the mean bond enthalpy for the C–H bond is | show 🗑
|
||||
| show | C2H6 + Cl2 --> C2H5Cl + HCl.
🗑
|
||||
| show | break the Cl Cl bond forming Cl• free radicals
🗑
