Draw the enol form of acetophenone 9. A compound has the formula CllO, with all the following characteristics: a) It has a band at 1700 cm in the IR. What does this tell you? b) It gives a negative 2,4-DNP test. What does this tell you? c) Its' H NMR consists of: 7.0-75 (S H, multiplet) lo 2.2 (3 H, singlet) What is the structure of this compound? 10. Show the steps necessary to carry out this transformation. CHy CH TO NO2Explanation / Answer
Ans 6 : a) (CH3)3N
The boiling point of amines can be explained on th basis of intermolecular association of molecules present between the molecules as a result of hydrogen bonding. Since tertiary amine has no free hydrogen available for the hydrogen bonding , it has the lowest boiling point of all others.
