Estimate the heat released when 1-butene(CH3CH2CHCH2) reacts with bromine to give CH3CH2CHBrCH2Br. Bond enthalpies are CH : 412 kJ/mol; CC : 348 kJ/mol;CC : 612 kJ/mol; CBr : 276 kJ/mol;BrBr : 193 kJ/mol.
1.317 kJ/mol
2.507 kJ/mol
3.95 kJ/mol
4.288 kJ/mol
5.181 kJ/mol
Explain the hybridisation of electron orbitals in a carbon atom (sp, sp2 and sp3), giving a detailed explanation,
supported by suitable examples, of how sigma (s) and pi (p) bonds are formed. 2 Explain why alkenes are much more
reactive than alkanes towards chlorine (C12) or bromine (Br2) in the dark at room temperature, and why alkanes do not
react with HCI (g) or HBr (g) whereas alkenes do. please provide a diagram as well
The energy difference between a tert-butyl group going from equatorial to axial in a cyclohexane is 18.3 kJ/mol. When two of the carbon atoms are replaced with oxygen atoms (molecule B) the energy difference between the two chair conformations drops to 5.9 kJ/mol. Explain this difference. (Hint: Consider what makes putting groups axial unfavorable).
