Haloalkanes and Haloarenes

Which one of the following alkenes when treated with HCl yields majorly an anti Markovnikov product?

The correct pair(s) of the ambident nucleophiles is(are) (A) AgCN/KCN (B) RCOOAg/RCOOK (C) AgNO₂/KNO₂ (D) AgI/KI

The isomeric deuterated bromide with molecular formula $$\mathrm{C_4H_8DBr}$$ having two chiral carbon atoms is

Assertion A : Hydrolysis of an alkyl chloride is a slow reaction but in the presence of NaI, the rate of the hydrolysis increases. Reason R : I$$^{-}$$ is a good nucleophile as well as a good leaving group. In the light of the above statements, choose the correct answer from the options given below

The pair from the following pairs having both compounds with net non-zero dipole moment is

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : Haloalkanes react with KCN to form alkyl cyanides as a main product while with $\mathrm{AgCN}$ form isocyanide as the main product. Reason (R) : $\mathrm{KCN}$ and $\mathrm{AgCN}$ both are highly ionic compounds. In the light of the above statements, choose the most appropriate answer from the options given below :

The correct statement regarding nucleophilic substitution reaction in a chiral alkyl halide is ;

Alkyl halide is converted into alkyl isocyanide by reaction with

Given below are two statements: Statement - I: High concentration of strong nucleophilic reagent with secondary alkyl halides which do not have bulky substituents will follow $$\mathrm{S}_{\mathrm{N}}{ }^2$$ mechanism. Statement - II: A secondary alkyl halide when treated with a large excess of ethanol follows $$\mathrm{S}_{\mathrm{N}}{ }^1$$ mechanism. In the light of the above statements, choose the most appropriate from the options given below:

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : $$\mathrm{S}_{\mathrm{N}} 2$$ reaction of $$\mathrm{C}_6 \mathrm{H}_5 \mathrm{CH}_2 \mathrm{Br}$$ occurs more readily than the $$\mathrm{S}_{\mathrm{N}} 2$$ reaction of $$\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{Br}$$. Reason (R) : The partially bonded unhybridized p-orbital that develops in the trigonal bipyramidal transition state is stabilized by conjugation with the phenyl ring. In the light of the above statements, choose the most appropriate answer from the options given below :
