Which of the following compounds has the shortest average C-C bond length? Benzene Cyclohexene Cyclohexane O Cyclohexadiene Which of the following statement(s) is(are) true? Select all that apply: When two atoms are bonded together, the distance between atoms is the same all the time. In the IR spectrum, carbonyl groups (C=O) have strong sharp peaks ranging from 1700 cm 1 to 1750 cm-1. When a molecule absorbs an IR radiation, electrons are excited within the molecule and each absorbed electron creates a band in the molecules IR spectrum. IR spectroscopy is useful in confirming the structure of the analyzed compound. Molecule N2 does not absorb IR radiationarrow_forward

You do not have to consider stereochemistry. You do not have to explicitly draw H atoms.arrow_forwardThe functional groups in an organic compound can frequently be deduced from its infrared absorption spectrum. A compound containing no nitrogen exhibits strong, broad absorption across the 2500-3300 cm³¹ region, accompanied by 2200 (w) and 1715 (s) cm-¹ bands. Relative absorption intensity: (s)=strong, (m)=medium, (w)=weak. What functional class(es) does the compound belong to? List only classes for which evidence is given here. Attach no significance to evidence not cited explicitly. Do not over-interpret exact absorption band positions. None of your inferences should depend on small differences like 10 to 20 cm³¹.
