Best method for preparation of
by williamson's ether synthesis is
3º alkyl halide react with sodium methoxide and gives alkene not ether because reaction will be elimination not substitution
In the acid catalyzed dehydration of alcohols to alkenes, the intermediate species formed is
Corbocation as intermidiate
Most reactive towards SN1 reaction
rate of SN1 α stability of carbocation reactivity order of Alkyl halide towards SN1 reaction
Most reactive towards SN2 reaction ?
[rate of SN2 a (less hindered T.S)]
reactivity order of Alkyl halide towards SN2 reaction
Most reactive towards E2 reaction ?
Most reactive towards E2 is t-bulyl chloride
It gives more stable alkene
Most reactive towards E1 reaction ?
Most reactive towards E1 is also t - butyl chloride because it gives most stable carbocation
