Explanation:
**[JEE MAINS 2020
HALOALKANES AND HALOARENES
91105
The hydrolysis reaction that takes place at the slowest rate, among the following is
1
2
3
4
Explanation:
Aryl halides don't show NSR easily at room temperature.
**[Odisha NEET 2019]**
HALOALKANES AND HALOARENES
91106
Neopentyl bromide, undergoes dehydrohalogenation to give alkenes even though it has no hydrogen. This is due to
1 E2 mechanism
2 E1 mechanism
3 Rearrangement of carbocations by E1 mechanism
4 mechanism
5 E1 mechanism
Explanation:
Neopentyl bromide give a carbocation as intermediate which undergo for rearrangement and show mechanism (Even has no atom).
**[Kerala CEE-2018]**
HALOALKANES AND HALOARENES
91107
The compound which does not lead to nitrile by substitution with is
1 benzyl chloride
2 ethyl chloride
3 isopropyl chloride
4 chlorobenzene
5 isobutyl chloride
Explanation:
In chlorobenzene, the lone pairs of electron on the chlorine atom are delocalized on the benzene ring a result acquires some double bond character, hence difficult to break or substitute.
