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 correct IUPAC name for the following structure is:
1. 2-Chloro-3-methylbutane
2. 3-Chloro-2-methylbutane
3. 2-Chloro-1-methylbutane
4. 3-Chloro-1-methylbutane
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:
1. Nucleophiles have equal atomic weight.
2. Nucleophiles have only five electrons.
3. Nucleophiles have two nucleophilic sites.
4. Nucleophiles have two electrophilic sites.
