Describe the chemical reactions of haloalkanes.

The correct order of reactivity of $CH_3Br$ in methanol with the following nucleophiles is:
$F^{-}, I^{-}, C_2H_5O^{-}$ and $C_6H_5O^{-}$

Which of the following will give acetaldehyde upon reaction with aqueous $KOH$?

The major product formed in the dehydrohalogenation reaction of $2-Bromopentane$ is $Pent-2-ene$. This product formation is based on?

Given below are two statements:
Statement $I$: The conversion $CH_3-CH_2-CH_2-CH_2-Cl \xrightarrow{OH^{-}} CH_3-CH_2-CH_2-CH_2-OH + Cl^{-}$ proceeds well in a less polar medium.
Statement $II$: The conversion $(CH_3)_3C-Cl \xrightarrow{OH^{-}} (CH_3)_3C-OH + Cl^{-}$ proceeds well in a more polar medium.
In the light of the above statements,choose the correct answer from the options given below.

Acetone is mixed with bleaching powder to give
