Why `S_(N^(1))` reactions are favourable in polar solvents?

S_N2 reactions are

Aliphatic nucleophilic substitution mainly takes place by two mechanisms (i.e) SN^1 & SN^2 Primary halides mainly undergo by SN^2 mechanism and are favourable in polar aprotic solvents. SN^1 reactions takes place mainly by tertiary halide and are more favourable in polar protic solvents, In case of tertiary halides, E_1 comes competition to SN^1 reaction. Keeping in view of these general points, answer the following questions (+)C_6H_5CH(CH_3)Cl to (pm) C_6H_5CH(OH)CH_3 in which of the following solvents, the above reaction is most favourable

Which type of compounds are more soluble in polar solvents ?

Which of the following compounds under goes predominantly S_N2 reaction with a NaOH in polar aprotic solveats

Predict the order of reactivity of the following compounds in S_(n^(1)) and S_(N^(2)) reactions : The four isomeric bromobutanes,

Acrylic paints are soluble in: a) polar solvents b) non-polar solvents

Predict the order of reactivity of the compounds in S_(N)1 and S_(N) 2 reactions . The four isomeric bromobutanes

(A): S_(N^(2)) reaction takes place in single step. (R): S_(N^(2)) reaction involves the reactivity order of alkyl halides as 1^@ gt 2^@ gt 3^@ halides.

SN^2 reactions of alkyl halides is a bimolecular reaction which take place through formation of a transition state. The rate of reaction depends on the concentration of alkyl halide and nucleophile.The reaction is favoured by strong nucleophlie in polar aprotic solvents. In which of the following solvents SN^2 reaction is more favourable
