trans-2-Butene does not exhibit a signal in the double-bond region of the spectrum (1600–1850 cm-1); however, IR spectroscopy is

still helpful in identifying the presence of the double bond. Select the other signal that would indicate the presence of a C= C bond.

Answer:

The other signal that would indicate the presence of a C= C bond appears close to 3100 cm^{-1}.

Explanation:

Bands that appear above 3000 cm^{-1}  are often unsaturation diagnoses suggest. The band at 3000- 3100 cm^{-1} is characteristics for C-H stretching frequencies and normally is overlaps with the ones for alkanes because it is a band of weak intensity.

A sample of carbon-12 has a mass of 6.00 g. How
dexar [7]

Answer:

#atoms C-12 = 3.01 x 10²³

Explanation:

Convert grams to moles and multiply by Avogadro's Number.

6 g C-12 = (6g/12g·mol⁻¹) = 0.50 mol C-12

No. C-12 atoms in 0.50 mol C-12 = 0.50 mol C-12 x 6.02E23 atoms/mole = 3.01E23

Which monomer gives a greater yield of polymer, 5-hydroxypentanoic acid or 6-hydroxyhexanoic acid? Explain your choice.
LekaFEV [45]

Answer:

6-hydroxyhexanoic acid

Explanation:

5-hydroxypentanoic acid will form a 7 member group, while 6-hydroxyhexanoic acid will form a 6 member group.

In polymerization, polymers with 6 member groups are more stable than the ones with 7 member groups. This means that 6-hydroxyhexanoic acid will have a higher chance of polymerization, and therefore give a greater yield of polymers, than 5-hydroxypentanoic acid.
