Mock Test 1 — Haloalkanes and Haloarenes

Aryl halide is less reactive than alkyl halide toward $S_N$ because:

Major product of $CH_3CH_2OH + SOCl_2$:

Most reactive halide in $S_N2$:

Sandmeyer reaction needs:

$C_2H_5Br + AgF \to$:

Finkelstein reaction product when $CH_3CH_2Cl + NaI$ in acetone:

Inversion of configuration occurs in:

Stable carbocation:

Aldol cleavage of haloform: $CHCl_3$ on hydrolysis gives:

Saytzeff's rule applies in:

Number of halogen atoms in chloroform:

Oxidation state of C in $CCl_4$:

Number of moles of HCl released when $CHCl_3$ converts to $COCl_2$:

Assertion (A): $S_N1$ shows racemization. Reason (R): Planar carbocation intermediate is attacked equally from both faces.

Assertion (A): $p$-nitrochlorobenzene undergoes nucleophilic substitution more easily than chlorobenzene. Reason (R): $-NO_2$ group stabilizes the Meisenheimer intermediate by withdrawing electron density.
