what is the stretching frequency (in cm⁻¹) of the following carbonyl?\n\no\n|\ncl\n\n1800\n1745\n1685\nnone of the above

Answer

Explanation:

Step1: Identify the carbonyl type

The given compound is an acyl - chloride with an aromatic ring attached to the carbonyl - containing carbon.

Step2: Recall carbonyl stretching frequency range

Acyl - chlorides have carbonyl stretching frequencies in the range of 1770 - 1815 $cm^{-1}$. The presence of the aromatic ring slightly lowers this value.

Answer:

1800
