Which has a lower characteristic stretching frequency, the C-H or C-D bond? Explain briefly.

Stretching Frequency

In vibrational spectroscopy, it refers to the frequency at which a bond between atoms oscillates, indicative of the strength and type of the bond.

C-H Bond

A chemical bond between a carbon and hydrogen atom, foundational in organic chemistry and present in all organic molecules.

C-D Bond

A chemical bond between a carbon atom and a deuterium atom, an isotope of hydrogen.

Master the basic notions of IR spectroscopy and its implementation in discerning distinct molecular bonds and compounds.
Understand and explain the consequences that factors such as the strength of bonds, the mass of atoms, and the dipole moment have on IR spectral information.

Verified Answer

Final Answer :

C-D; heavier atoms vibrate more slowly
