Question

Integrated Problem 07.93b Bromotriphenylmethane (compound 1) can be converted to 2a or 2b or 2c upon treatment with the appropriate nucleophile. Ph Ph ROH Br Ph OR Ph Ph 2 2a: R=H 2b: R=CH3 2c: R=CH2CH3 Ph Ph = IR spectroscopy is an ideal tool for monitoring the conversion of 1 to 2a, while other forms of spectroscopy will be better suited for monitoring the conversion of 1 to 2b or 1 to 2c. Select the reasons why IR is an ideal tool ONLY for conversion of 1 to 2a Product 2a but NOT product 2b and 2c has an ether (OR) functional group that can be EASILY identified by a signal in the range of 1000-1100 cm Product 2c but NOT product 2a and 2b has an alcohol (OH) functional group that can EASILY be identified by a signal in the range of 3200-3600 cm-1 IR is the QUICKEST and BEST way to distinguish product 2a from reactant 1 IR is the QUICKEST and BEST way to distinguish product 2b from reactant 1. Product 2b but NOT product 2a and 2c has an ether (OR) functional group that can be EASILY identified by a signal in the range of 1000-1100 cm1 O IR is the QUICKEST and BEST way to distinguish product 2c from reactant 1. Product 2a but NOT product 2b and 2c has an alcohol (OH) functional group that can EASILY be identified by a signal in the range of 3200-3600 cm Product 2c but NOT product 2a and 2b has an ether (OR) functional group that can be EASILY identified by a signal in the range of 1000-1100 cm Product 2b but NOT product 2a and 2c has an alcohol (OH) functional group that can be EASILY identified by a signal in the range of 3200-3600 cm

Explanation / Answer

07-93

In the above shown reaction, triphenylmethyl bromide (1) is converted to triphenylmethanol (2a).

IR is the quikest and best way to distinguish product 2a from reactant 1.

IR-spectroscopy but not product 2b and 2c has an alcohol (OH) functional group that can be easily be identified by a signal in the range of 3200-3600 cm-1.

Product 2a
