cle $T$ for a true statement and $F$ for a false statement.

Increasing the concentration of the nucleophile increases the rate of an $S_{N}1$ reaction

ii$.$ Tertiary alkyl halides react faster than a secondary and primary alkyl halide in an E$2$ reaction

iii. Strong bases are good leaving groups

iv$.$ The rate determining step of an $S_{N}1$ reaction is the formation of the carbocation

A polar protic solvent will stabilize the transition state of the rate

v$.$ determining step of an $S_{N}1$ reaction more than it stabilizes the reactants

vi$.$ Electrophiles are chemical species that accept an electron pair from an electron rich center

vii. Benzene undergoes bimolecular electrophilic substitution reactions Rate $=k[$alkyl halide$][$nucleophile$/$base$]$ is the rate law that

viii. corresponds to the reaction between tert$-$butyl chloride and hydroxide ion

ix$.$ Secondary alkyl halides react faster than primary alkyl halides in $S_{N}2$ reactions

x$.$ If an $S_{N}2$ reaction takes place at an asymmetric center, it yields a

T $,$ F

xi$.$ Iodide ion $(I^{-})$is a better nucleophile than chloride ion $(C{l}^{-})$in a polar protic solvent.

xii. Substituted alkenes are less stable than non$-$substituted ones since the latter have less steric hindrance.

xiii. Electrophilic addition of a hydrogen halide to an alkene is a regioselective reaction.

xiv. When the electrophilic addition to $2-$butene leads to the formation of a chirality centre, the product is a racemic mixture.
