The major product formed in the dehydrohalogenation reaction of 2-Bromo pentane is Pent-2-ene. This product formation is based on:
1. | Hofmann Rule | 2. | Huckel's Rule |
3. | Saytzeff's Rule | 4. | Hund's Rule |
Primary alkyl halide C4H9Br(A) reacted with alcoholic KOH to give compound (B). Compound (B) is reacted with HBr to give (C), and it was found that C is an isomer of (A).
(A) with sodium metal, gives compound (D), C8H18
which is different from the compound formed when n-butyl bromide is reacted with sodium.
Compound (A) is :
1. 2-Methylpropene
2. Isobutyl bromide
3. 2,5-Dimethylhexane
4. 2-Bromo-2-methylpropane
p-Dichlorobenzene has a higher melting point than those of o- and m-isomers because :
1. | More energy is required to break the crystal lattice of m-dichlorobenzene |
2. | More energy is required to break the crystal lattice of p-dichlorobenzene |
3. | More energy is required to break the crystal lattice of o-dichlorobenzene |
4. | None of the above |
The correct statement regarding ambident nucleophiles is:
