Introduction And Physical Properties

The correct order of increasing C-X bond reactivity toward nucleophiles among the following is:

I		II
III		IV

1.	I < II < IV < III	2.	II < III < I < IV
3.	IV < III < I < II	4.	III < II < I < IV

Find the correct sequence of the bond enthalpy of the "C-X" bond among the following:

1. CH₃-F < CH₃-Cl > CH₃-Br > CH₃-I

2. CH₃-Cl > CH₃-F > CH₃-Br > CH₃-I

3. CH₃-F < CH₃-Cl < CH₃-Br < CH₃-I

4. CH₃-F > CH₃-Cl > CH₃-Br > CH₃-I

The following compound would be classified as:

1.	Vinylic halide	2.	Benzylic halide
3.	Aryl halide	4.	Allylic halide
