The empirical formula of a compound is ch. it's molar mass is 52.07 g/mole. What is its molecular formula
Rina8888 [55]
For this item, we find first the mass of the compound with the empirical formula. That is,
                             molar mass = 12 (for C) + 1 (for H)
                                                   = 13 g/mole
Then, we divide the given mass of the molecular formula by the mass of the empirical formula. 
                                    n = 52.07 / 13 = 4
Therefore, the molecular formula is C₄H₄.

Acenaphthylene, a hydrocarbon that is a constituent of a coal tar, is 94.71% and has a molar mass of 152.19 g/mol. What are the
dolphi86 [110]

Answer:

From what I personally know, Acenaphthylene 75%. Empirical Formula (Hill Notation): C12H8. CAS Number: 208-96-8. Molecular Weight: 152.19. Beilstein: 774092. EC Number:

Explanation:

Acenaphthylene, a polycyclic aromatic hydrocarbon is an ortho- and peri-fused tricyclic hydrocarbon. The molecule resembles naphthalene with positions 1 and 8 connected by a -CH=CH- unit. It is a yellow solid. Unlike many polycyclic aromatic hydrocarbons, it has no fluorescence. Acenaphthylene/Formula is C12H8.

I'm not sure if this will help you but this is what I know so I hope it does :)

Choose the molecule(s) that will only show two signals, with an integration ratio of 2:3, in their 1H NMR spectrum.
mrs_skeptik [129]

The question is missing the molecules in which the integration ratio of 2:3 will be observed. The complete question is given in the attachment.

Answer:

Molecule (a), (c), and (f) will show two peaks with the integration ratio of 2:3 in their 1H NMR spectrum

Explanation:

In the 1H NMR spectrum, the peak area is dependent on the number of hydrogen in a specific chemical environment. Hence, the ratio of the integration of these signals provides us with the relative number of hydrogen in two peaks. This rationale is used for the assignment of molecules that will give 2:3 integration ratio in the given problem.

  • Molecule (a) have two CH₂ and three CH₃ groups. Hence, it will give two peaks and their integration ratio becomes 2:3 (Answer)
  • Molecule (b) contains three chemical environments for its hydrogen atoms
  • Molecule (c) have a single CH₂ and CH₃ group giving integration ratio of 2:3 (Answer)
  • Molecule (d) will give two peaks but their ratio will be 1:3 because of two hydrogens of CH₂ and six hydrogens from two CH₃ groups
  • Molecule (e) have three CH and three CH₃ groups, so their ratio will become 1:3
  • Molecule (f) contains four CH and two CH₃ groups, giving two peaks. So, the integration ratio of their peaks is 2:3 (Answer)
  • Molecules
  • (g)
  • and
  • (h)
  • both have two CH and two CH₃ groups giving two peaks with the integration ratio of 1:3
