Term
| At what point would you expect to find the CH2 signal on an IR graph? |
|
Definition
It's not a point but a range. CH2 signals are typically greater than 1400 but they normally don't go far from 1400 (maybe up to 1500 at most). Distinguishing between CH2 and CH3 can be very tricky |

Term
| At what point could you expect to find the signal for CH3 on an IR graph? |
|
Definition
It's not a point but a range. CH3 will typically be less than 1400 but they won't go too far, maybe down to 1300 at the most. Distinguishing between these and CH2 signals can be tricky depending on relative shift of the machine that you use |

Term
| At what point could you expect to find the signal for an isopropyl group? |
|
Definition
It wouldn't be a point, it would be a range instead. The signal would typically be given somewhere below 1400 but typically not below 1300. DON'T confuse this signal with CH3! |

Term
| At what point would the signal for O-H be found on an IR graph and what else is important to note? |
|
Definition
The signal will typically be found around 3400 but the dip that this bond forms in the graph is extremely obvious; it is very broad (sometimes spanding as much as 700-800 in length) and typically doesn't have many sharp peaks |

Term
| At what point would the signal for C(resonance single to double)C bond be found on an IR chart? |
|
Definition
It would actually give off 2 points, about 1500 and 1600 |

Term
| At what point would the signal for C=O be found on an IR graph? |
|
Definition
1700 (this peak will be very distinct and sharp!) |
