Rate of reaction increases exponentially with concentration
Rate equation is experimentally determined. So, you can't directly write $r=k[A][B]$ (where r is rate, k is rate constant). Probably you might have performed first order reaction. For which $r=k[A]=\f …

Why are tertiary alkyl halides obtained in higher yield than secondary or primary during fre...
From my textbook:
Halogens ($\ce{Cl_2}$ and $\ce{Br_2}$ ) react with alkanes in the presence of ultraviolet light to form haloalkanes.This reaction is free radical substitution and gives a mixture …

Can we prepare alkyl chloride or alkyl bromide by Finkelstein reaction?
My book says:
Finkelstein reaction is particularly useful for preparing iodoalkanes. The iodoalkanes are obtained by heating chloro or bromoalkanes with a concentrated solution of sodium iodide i …

Reasons for dry conditions in substituition reactions with benzene
Benzene and other aromatic hydrocarbons are immisible with water. So, probably there is no problem with benzene if we there is moisture.
In most of the substitution reactions which benzene undergo, …

In the reversible reactions of acyl substitution, how do backward reactions happen by being ...
Consider this mechanism for acyl substitution by nucleophilic addition-elimination:
To start with, the nucleophile having a lone pair of electrons attacks carbon (because of oxygen being more elect …

How does the inductive effect, explain the reactivity of tertiary alcohols with halogen acids?
The reactions of primary and secondary alcohols with halogen acids ($\ce{HX}$, where $\ce{X}$=halogen) require the presence of a catalyst, $\ce{ZnCl_2}$. With tertiary alcohols, the reaction is conduc …
