Chemistry Homework Assistance
QuestionAI's chemistry problem solver is a middle school chemistry tutoring tool that summarises key chemical reactions and equations in real-time, featuring a robust learning system to empower even those with a weak foundation in chemistry.
You needn't fret over the elemental properties of the periodic table anymore. Here, you can effortlessly access chemical reactions and reaction principles corresponding to each element. Deductive reasoning from microscopic phenomena to discern the original structure of molecules and atoms is a research technique we staunchly champion.
- Copper is a good conductor of electricity and of what else?
- Q2 Use the mass spectrum below to work out the structure of the molecule. HINT: The molecule is an alkene. Q3 Identify a fragment ion that will appear in the mass spectrum of butan-2-ol but won't appear in the mass spectrum of butan-1-ol. 1 Write equations to show how the following molecules are converted into their molecular ions, and predict the m/2 value for their molecular ions. a nonane (2 morks) b butan-1-ol (2 marks) 2 Explain why there sometimes a peak in the spectrum after the molecular ion peak. 3 Use the spectra provided to identify the molecular ion peak and hence the molecular mass of compound A and compound B. corrpound A (2 marks) 4. Identify the fragments of m/z=29 and m/2=31 formed from the molecular ion of butan-1-ol 5 The mass spectrum of the ketone, hexan-2-one has a large fragment ion at m/z=43 a Suggest two possible structures for this fragment ion. b. Write an equation for the formation of each structure from the molecular ion. (2 marks) (2 marks) (2 marks) (4 marks)
