What will be the product of alkaline hydrolysis of $2, 2$ -dichloropropane?

Which of the following statement is correct for ${\mathrm{SN}}^2$ mechanism?

What is the type of following reaction?

In the above reaction the attack of a nucleophile would be from which side?

Major product of the reaction :-   ${\left({\mathrm{CH}}_3\right)}_3\mathrm{C}-\mathrm{Cl}+{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{ONa}⟶$ would be :-

$\mathrm{Assertion} :-$ Chlorobenzene and benzyl chloride can be distinguished by treatment with ${\mathrm{AgNO}}_3$.

$\mathrm{Reason} :$ Chlorobenzene does not gives white ppt with ${\mathrm{AgNO}}_3$ due to resonance.

$\mathrm{Assertion} :-$ Benzyl phenylether forms phenol and benzyl iodide with $\mathrm{HI}$

$\mathrm{Reason} :-$ Because benzyl carbocations is more stable than phenyl.carbocation.

Assertion (A): The product of reaction of $2-$Methyl cyclo hexanol with $\mathrm{HBr}$ at room temperature is $1-$Bromo$-1-$methyl cyclo hexane.

Reason (R): Generally dehydration occur and product is $1-$methyl cyclo hexene.
