Which compound would be expected to show intense IR absorption at 2710 and 1705 cm-1? (Ph = phenyl group)

Chemistry
1 answer:
Serhud [2]4 years ago
7 0

Answer:

B. PhCHO

Explanation:

Every organic group shows a characteristic IR absorption at certain wavelength . With the help of these absorption spectra we can identify the group present on organic molecules .

The wave number of 2710 cm⁻¹ is absorbed by aldehyde bond stretching .

The wave number of 1705 cm⁻¹ is shown by conjugated aldehyde . So the most likely compound among given compounds is PhCHO .

B directly; inversely

Pressure and volume have an inverse relationship (when one increases the other increases) while volume and temperature are direct (if one increases so does the other)

Note: these relationships are only true if other factors are constant such as the temperature, and amount (in moles).
