The second compound - CORRECT ANSWER✅✅Determine which C=C bond will produce a stronger
signal.
The second compound - CORRECT ANSWER✅✅Determine which C=C bond will produce a stronger
signal.
The broad signal between 3200 and 3600 cm⁻¹ is characteristic of an alcohol (ROH). - CORRECT
ANSWER✅✅Is this image consistent with the structure of an alcohol, a carboxylic acid, or neither?
This spectrum lacks broad signals above 3000 cm⁻¹, so the compound is neither an alcohol nor a
carboxylic acid (both of which produce broad signals that reach as high as 3600 cm⁻¹). - CORRECT
ANSWER✅✅Is this image consistent with the structure of an alcohol, a carboxylic acid, or neither?
The extremely broad signal that extends from 2200 to 3600 cm⁻¹ is characteristic of the O-H stretching
of a carboxylic acid (RCO2H). The signal just above 1700 cm⁻¹ is also consistent with a carboxylic acid (for
the C=O bond of the carboxylic acid). - CORRECT ANSWER✅✅Is this image consistent with the structure
of an alcohol, a carboxylic acid, or neither?
This spectrum lacks broad signals above 3000 cm , so the compound is neither an alcohol nor a
carboxylic acid (both of which produce broad signals that reach as high as 3600 cm⁻¹). - CORRECT
ANSWER✅✅Is this image consistent with the structure of an alcohol, a carboxylic acid, or neither?
The broad signal between 3100 and 3600 cm is characteristic of an alcohol (ROH). - CORRECT
ANSWER✅✅Is this image consistent with the structure of an alcohol, a carboxylic acid, or neither?
The extremely broad signal that extends from 2200 to 3600 cm⁻¹ is characteristic of the O-H stretching
of a carboxylic acid (RCO2H). The signal around 1700 cm⁻¹ is also consistent with a carboxylic acid (for
the C=O bond of the carboxylic acid). - CORRECT ANSWER✅✅Is this image consistent with the structure
of an alcohol, a carboxylic acid, or neither?
, The strong signal just above 1700 cm with the stretching of the carbonyl group (C=O) of a ketone. -
CORRECT ANSWER✅✅Is this image consistent with the structure of a ketone, an alcohol, a a carboxylic
acid, a primary amine, or a secondary amine?
The extremely broad signal that extends from 2200 to 3600 cm⁻¹ is characteristic of the O-H stretching
of a carboxylic acid (RCO2H). The signal just above 1700 cm⁻¹ is also consistent with a carboxylic acid (for
the C=O bond of the carboxylic acid). - CORRECT ANSWER✅✅Is this image consistent with the structure
of a ketone, an alcohol, a a carboxylic acid, a primary amine, or a secondary amine?
The signal at approximately 3400 cm⁻¹ is consistent with the stretching of the N-H bond of a secondary
amine. - CORRECT ANSWER✅✅Is this image consistent with the structure of a ketone, an alcohol, a a
carboxylic acid, a primary amine, or a secondary amine?
The two signals at 3350 and 3450 cm are consistent with the stretching of the N-H bonds (symmetric
and asymmetric) of a primary amine. - CORRECT ANSWER✅✅Is this image consistent with the structure
of a ketone, an alcohol, a a carboxylic acid, a primary amine, or a secondary amine?
The strong signal just above 1700 cm⁻¹ is consistent with the stretching of the carbonyl group (C=O) of a
ketone. - CORRECT ANSWER✅✅Is this image consistent with the structure of a ketone, an alcohol, a a
carboxylic acid, a primary amine, or a secondary amine?
